Subject: media: atmel: atmel-isc: reworked white balance feature

Reworked auto white balance feature (awb) to cope with all four channels.
Implemented stretching and grey world algorithms.
Using the histogram, the ISC will auto adjust the white balance during
frame captures.
Because each histogram needs a frame, it will take 4 frames for one adjustment.
When the gains were updated by previous code, the registers for the gains
were updated only on new streaming start. Now, after each full histogram the
registers are updated with new gains.
Also, on previous code, if the streaming stopped but not all 3 histograms
finished, a new histogram was started either way. This used to lead to an
error "timeout to update profile" when streaming was stopped.
According to the hardware, histogram can only work together with the capture,
not independently.

Subject: media: atmel: atmel-isc: add support for DO_WHITE_BALANCE

This adds support for the 'button' control DO_WHITE_BALANCE
This feature will enable the ISC to compute the white balance coefficients
in a one time shot, at the user discretion.
This can be used if a color chart/grey chart is present in front of the camera.
The ISC will adjust the coefficients and have them fixed until next balance
or until sensor mode is changed.
This is particularly useful for white balance adjustment in different
lighting scenarios, and then taking photos to similar scenery.
The old auto white balance stays in place, where the ISC will adjust every
4 frames to the current scenery lighting, if the scenery is approximately
grey in average, otherwise grey world algorithm fails.
One time white balance adjustments needs streaming to be enabled, such that
capture is enabled and the histogram has data to work with.
Histogram without capture does not work in this hardware module.

To start the one time white balance procedure:
v4l2-ctl --set-ctrl=do_white_balance=1

This feature works only if the sensor is streaming RAW data, as the hardware
supports a histogram only for RAW bayer components.

If the auto white balance is enabled, do_white_balance does nothing.
If the streaming is disabled, or the sensor does not output RAW data, the
control is inactive.

User controls now include the do_white_balance ctrl:

Subject: media: atmel: atmel-isc: make try_fmt error less verbose

In case the sensor refuses to set the format, avoid printing the error
message that no compatible format was found.
This means that the try_fmt will be less verbose.
The error will be printed only if really a format cannot be found.
Some application try all possible formats in a row (gstreamer e.g.)
which will flood the console with error messages until a working one is found.

verbose debug logging. Register access level logging is of limited

 - if no frame was decoded, the reason (code) why
 - which decoded frame was returned, copied out by either rotator or VODA,
 - if no frame was returned, the reason (code) why, and
 - the output queue sequence number, which is only useful in case
   each queued coded buffer corresponds to exactly one frame.

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

actual_length != wlen is the only error path which does not generate an
error message. Adding an error message here allows to report a more
specific error and to remove the error reporting from the call sites.

Also clean up the error paths - in case of an error, the remaining
code is skipped, and ret is returned. Skip setting ret and return
immediately (no cleanup necessary).

Subject: media: cec: mark devnode as registered before actually registering it

The cec device node can be used right after it was created, but that
leaves a race condition where the device was created, but devnode->registered
was still false. So an ioctl() would result in an error.

So set it to true before calling cdev_device_add() and to false again if
cdev_device_add returned an error.

Subject: media: cec-gpio: use disable/enable_irq

Due to limitations in gpiolib it was impossible to disable the interrupt of
an input gpio and then switch it to gpio output and drive it. The only way
to achieve that was to free the interrupt first, then switch the direction.

When going back to gpio input and using interrupts to read the gpio pin you
had to request the irq again.

This limitation was lifted in gpiolib in kernel 4.20, but the cec-gpio driver
was still using the old workaround implementation.

This patch updates the cec-gpio driver to just enable and disable the irq.

Subject: media: cec: allow any initiator for Ping and Image/Text View On

Some displays pull down the HPD when in standby, but CEC is still
active and the display can be woken up by sending an Image View On
or Text View On CEC command. The CEC specification doesn't tell you
what the initiator should be for such a command (without a HPD it's
unclear if the CEC adapter can claim a logical address).

This patch allows any initiator value when there is no HPD for the
Image/Text View On commands and for the Ping command.

Subject: media: ov7740: fix vertical flip control

Setting the value of the V4L2_CID_VFLIP control is currently ignored.

Because V4L2_CID_HFLIP and V4L2_CID_VFLIP are independently controlled
in s_ctrl() but these controls belong to the same cluster and the first
control is V4L2_CID_HFLIP.

Fix it by not clustering these controls.  Also correct erroneous updating
register bit for vertical flip.

Subject: media: marvell-ccic: fix DMA s/g desc number calculation

The commit d790b7eda953 ("[media] vb2-dma-sg: move dma_(un)map_sg here")
left dma_desc_nent unset. It previously contained the number of DMA
descriptors as returned from dma_map_sg().

We can now (since the commit referred to above) obtain the same value from
the sg_table and drop dma_desc_nent altogether.

Tested on OLPC XO-1.75 machine. Doesn't affect the OLPC XO-1's Cafe
driver, since that one doesn't do DMA.

05fed81625bf ("[media] marvell-ccic: add MIPI support for marvell-ccic driver")
that claimed to add CSI2 turned on C0_EOF_VSYNC for parallel bus
without a very good explanation.

That broke camera on OLPC XO-1.75 which precisely uses a sensor on a
parallel bus. Revert that chunk.

Tested on an OLPC XO-1.75.

Subject: media: videobuf2-dma-sg: Prevent size from overflowing

buf->size is an unsigned long; casting that to int will lead to an
overflow if buf->size exceeds INT_MAX.

Fix this by changing the type to unsigned long instead. This is possible
as the buf->size is always aligned to PAGE_SIZE, and therefore the size
will never have values lesser than 0.

drivers/media/v4l2-core, it was moved to the current location after 4.14.

Subject: media: Kconfig: allow to select drivers if EMBEDDED

Embedded systems often connect to sensors or other multimedia
subdevices directly. Currently, to be able to select such a
subdevice (e.g. CONFIG_VIDEO_OV5640) disabling of the auto-
select config option is needed (CONFIG_MEDIA_SUBDRV_AUTOSELECT).

This is inconvenient as the ancillary drivers for a particular
device then need to be selected manually.

Allow to select drivers manually while keeping the auto-select
feature in case EXPERT (selected by EMBEDDED) is enabled.

From 2f39cce963637eee1c58740859c7c63356c29099 Mon Sep 17 00:00:00 2001

Subject: media: remove redundant 'default n' from Kconfig-s

'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.

Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:

    ...
    One side effect of (and the main motivation for) this change is making
    the following two definitions behave exactly the same:

        config FOO
                bool

        config FOO
                bool
                default n

    With this change, neither of these will generate a
    '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
    That might make it clearer to people that a bare 'default n' is
    redundant.
    ...

These two slice modes used by the V4L2_CID_MPEG_VIDEO_MULTI_SLICE_MODE
control had a silly typo:

V4L2_MPEG_VIDEO_MULTI_SICE_MODE_MAX_MB
V4L2_MPEG_VIDEO_MULTI_SICE_MODE_MAX_BYTES

SICE should be SLICE.

Rename these enum values, keeping the old ones (under #ifndef __KERNEL__)
for backwards compatibility reasons.

From c612e54fca55d9380c1378eaa623d74ed89b62db Mon Sep 17 00:00:00 2001
From: Hans Verkuil <hverkuil@xs4all.nl>
Date: Thu, 2 May 2019 09:42:31 -0400
Subject: media: move drivers/media/media-* to drivers/media/mc/mc-*

It is really weird that the media controller sources are all top-level
in drivers/media. It is a bit of a left-over from long ago when most
media sources were all at the top-level. At some point we reorganized
the directory structure, but the media-*.c sources where never moved
to their own directory.

So create a new mc directory and move all sources there. Also rename
the prefix from media- to mc-.

From 1753c7c4367aa1201e1e5d0a601897ab33444af1 Mon Sep 17 00:00:00 2001
From: Andrey Konovalov <andreyknvl@google.com>
Date: Thu, 2 May 2019 12:09:26 -0400
Subject: media: pvrusb2: use a different format for warnings

When the pvrusb2 driver detects that there's something wrong with the
device, it prints a warning message. Right now those message are
printed in two different formats:

1. ***WARNING*** message here
2. WARNING: message here

There's an issue with the second format. Syzkaller recognizes it as a
message produced by a WARN_ON(), which is used to indicate a bug in the
kernel. However pvrusb2 prints those warnings to indicate an issue with
the device, not the bug in the kernel.

This patch changes the pvrusb2 driver to consistently use the first
warning message format. This will unblock syzkaller testing of this
driver.

Subject: media: coda: Print a nicer device registered message

This is just a cosmetic change to print a more descriptive
message, to distinguish decoder from encoder:

So, instead of printing

  coda 2040000.vpu: codec registered as /dev/video[4-5]

With this change, the driver now prints

  coda 2040000.vpu: encoder registered as /dev/video4
  coda 2040000.vpu: decoder registered as /dev/video5

The mutex unlock in the threaded interrupt handler is not paired
with any mutex lock. Remove it.

This bug has been here for a really long time, so it applies
to any stable repo.

Subject: media: coda: Replace the threaded interrupt with a hard interrupt

The current interrupt handler is doing very little, and not doing
any non-atomic operations. Pretty much all it does is accessing
a couple registers, taking a couple spinlocks and then signalling
a completion.

There is no reason this should be a threaded interrupt handler,
so move the handler to regular hard interrupt context.

Subject: media: coda: Clear the interrupt reason

This commit clears the interrupt reason (INT_REASON) register
on the interrupt handler. Without this clearing, the CODA hardware
has been observed to get completely stalled on CODA980 variants,
requiring a pretty deep hardware reset.

The datasheet specifies that the INT_REASON register is set
by the CODA hardware, and should be cleared by the host.

While the CODA versions that are currently supported by this driver
don't seem to need this change, it's a really small change,
so it seems a wise thing to do to avoid hitting some
rare race-condition in the hardware.

Subject: media: rcar-csi2: Fix coccinelle warning for PTR_ERR_OR_ZERO()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use the PTR_ERR_OR_ZERO() macro instead of construct:

    if (IS_ERR(foo))
        return PTR_ERR(foo);

    return 0;

Fixing use-after-free within __v4l2_ctrl_handler_setup().
Memory is being freed with kfree(new_ref) for duplicate
control reference entry but ctrl->cluster pointer is still

Subject: media: vimc: fix component match compare

If the system has other devices being registered in the component
framework, the compare function will be called with a device that
doesn't belong to vimc.
This device is not necessarily a platform_device, nor have a
platform_data (which causes a NULL pointer dereference error) and if it
does have a pdata, it is not necessarily type of struct vimc_platform_data.
So casting to any of these types is wrong.

Instead of expecting a given pdev with a given pdata, just expect for
the device it self. vimc-core is the one who creates them, we know in
advance exactly which object to expect in the match.

Fixes: 4a29b7090749 ("[media] vimc: Subdevices as modules")

For this device udev->product is not initialized and accessing it causes a NULL pointer deref.

The fix is to check for NULL before strscpy() and copy empty string, if
product is NULL

Subject: media: cx25840: don't open-code cx25840_reset() inside
 cx25840_load_fw()

cx25840_load_fw() does the same thing as cx25840_reset(), only keeps
"is_initialized" flag so any further invocation of this function besides
the first one is a NOP.
Let's just call cx25840_reset() directly from cx25840_load_fw() instead of
open coding it there.

While we are at it, let's also improve comments about cx25840_load_fw()
so they are current and in the proper style (one of them even referred to a
non-existing cx25840 init operation).

Subject: media: cx25840: g_std operation really implements querystd operation

cx25840 driver g_std operation queries the currently detected video signal,
however this is what querystd operation should do, so let's rename the
handler.

None of the existing cx25840 driver users ever called the g_std operation,
one of them calls querystd on each of its subdevs but then the result is
only used to implement VIDIOC_QUERYSTD (as it should).

Subject: media: cx25840: add pin to pad mapping and output format
 configuration

This commit adds pin to pad mapping and output format configuration support
in CX2584x-series chips to cx25840 driver.

This functionality is then used to allow disabling ivtv-specific hacks and
configuration values (called a "generic mode"), so cx25840 driver can be
used for other devices not needing them without risking compatibility
problems.

Subject: media: cx25840: set_fmt operation should clamp out-of-range picture
 sizes

According to V4L2 API set_fmt subdev operation should not return an error
on out-of-range picture sizes, the values should be clamped instead to the
supported range.

The cx25840 datasheet says that the chip is capable of scaling down the
picture width and height, respectively, 16 and 8 times.
These values agree with what the old implementation enforced.

Subject: media: cxusb: implement Medion MD95700 digital / analog coexistence

This patch prepares cxusb driver for supporting the analog part of
Medion 95700 (previously only the digital - DVB - mode was supported).

Specifically, it adds support for:
* switching the device between analog and digital modes of operation,
* enforcing that only one mode is active at the same time due to hardware
limitations.

Actual implementation of the analog mode will be provided by the next
commit.

Subject: media: cxusb: add analog mode support for Medion MD95700

This patch adds support for analog part of Medion 95700 in the cxusb
driver.

What works:
* Video capture at various sizes with sequential fields,
* Input switching (TV Tuner, Composite, S-Video),
* TV and radio tuning,
* Video standard switching and auto detection,
* Radio mode switching (stereo / mono),
* Unplugging while capturing,
* DVB / analog coexistence.

What does not work yet:
* Audio,
* VBI,
* Picture controls.

Subject: media: cxusb: add raw mode support for Medion MD95700

This adds raw (unprocessed) BT.656 stream capturing support for the analog
part of Medion 95700.
It can be enabled by setting CXUSB_EXTENDEDMODE_CAPTURE_RAW flag in
parm.capture.extendedmode passed to VIDIOC_S_PARM.

Subject: media: uapi: Add H264 low-level decoder API compound controls.

Stateless video codecs will require both the H264 metadata and slices in
order to be able to decode frames.

This introduces the definitions for the structures used to pass the
metadata from the userspace to the kernel.

Subject: media: videobuf2-vmalloc: get_userptr: buffers are always writable

In vb2_vmalloc_get_userptr() the framevector is created with the
'write' argument set to false when vb2_create_framevec() is called
for OUTPUT buffers. So the pages are marked as read-only.

However, userspace will write to these buffers since it will fill
in the data to output. Since get_userptr is only called if the userptr
of the queued buffer has changed since the last time that same buffer
was queued, this will fail when the buffer contents is updated and the
buffer is queued again.

E.g., userspace fills buffer 1 with the output video and queues it.
The first time get_userptr is called and the pages are grabbed and
pinned in memory and marked read-only. The second time buffer 1 is
filled with different video data and queued again. Since the userptr
hasn't changed the get_userptr() callback isn't called again. Since
the pages were marked as read-only the new contents isn't updated.

Just always call vb2_create_framevec() with FOLL_WRITE to always
allow writing to the buffers.

Using USERPTR streaming with OUTPUT devices is almost never done. And
when it is done it is via v4l2-compliance and a driver like vim2m. But
since v4l2-compliance doesn't actually inspect the capture buffer and
compare it to the original output buffer, this issue was never noticed.

But the vicodec driver actually needs to parse the bitstream in the
OUTPUT buffers and any errors there will be immediately noticed. So
this time v4l2-compliance failed the USERPTR streaming test.

Subject: media: cxusb-analog: Fix some coding style issues

This is a new file, so the best moment to make it to follow
Kernel coding style is now.

This patch was partially generated with:

	./scripts/checkpatch.pl --fix-inplace --strict -f drivers/media/usb/dvb-usb/cxusb-analog.c

And manually checked and adjusted to avoid any warnings.

Subject: media: cxusb: fix several coding style issues

As this driver had a major change, let's take the opportunity
and do some coding style cleanup, in order to make it compliant
with Kernel's style.

This patch was partially done with the help of two tools:

	./scripts/checkpatch.pl --fix-inplace --strict
	astyle --indent=tab=8 --style=linux

But manually adjusted in order to fit our style.

Subject: media: cx25840: Address several coding style issues

As we did a major change on this file, let's take the moment
to cleanup several coding style issues on it.

This patch was partially done with the help of two tools:

	./scripts/checkpatch.pl --fix-inplace --strict
	astyle --indent=tab=8 --style=linux

But manually adjusted in order to fit our style.

Subject: media: sun6i: Support A83T variant

The A83T SoC has a camera sensor interface (known as CSI in Allwinner
lingo), which is similar to the one found on the A64 and H3. The only
difference seems to be that support of MIPI CSI through a connected
MIPI CSI-2 bridge.

Add support for this variant.

Subject: media: omap3isp: Don't rely on devm for memory resource management

devm functions are fine for managing resources that are directly related
to the device at hand and that have no other dependencies. However, a
process holding a file handle to a device created by a driver for a device
may result in the file handle left behind after the device is long gone.
This will result in accessing released (and potentially reallocated)
memory.

Instead, manage the memory resources in the driver. Releasing the
resources can be later on bound to e.g. by releasing a reference.

platform_device_id are not supposed to change at runtime. All functions
working with platform_device_id provided by <linux/platform_device.h>
work with const platform_device_id. So mark the non-const structs as
const.

Subject: media: dvb-usb/cxusb-analog.c: fix coccinelle warning, use ktime.h

This patch fixes a coccinelle warning and includes ktime.h instead of
timekeeping.h. The first includes the latter, but the latter doesn't
exist before 3.17, causing problems for our compat build. It's easier
to just use ktime.h instead.

coccinelle warnings: (new ones prefixed by >>)

Subject: media: platform: ao-cec-g12a: disable regmap fast_io for cec bus
 regmap

With fast_io enabled, spinlock_irq is used for read/write operations,
thus leading to :
BUG: sleeping function called from invalid context at [snip]/ao-cec-g12a.c:379
 in_atomic(): 1, irqs_disabled(): 128, pid: 1451, name: irq/14-ff800280

Simply remove fast_io to use mutexes instead.

Subject: media: v4l2: Make sure all drivers set _MPLANE caps in
 vdev->device_caps

This is needed if we want the core to be able to check _MPLANE support
without having to call the ->vidioc_querycap() hook.

Subject: media: v4l2: Get rid of ->vidioc_enum_fmt_vid_{cap, out}_mplane

Support for multiplanar and singleplanar formats is mutually exclusive,
at least in practice. In our attempt to unify support for support for
mplane and !mplane in v4l, let's get rid of the
->vidioc_enum_fmt_{vid,out}_cap_mplane() hooks and call
->vidioc_enum_fmt_{vid,out}_cap() instead.

Subject: media: media/radio: set device_caps in struct video_device

Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.

That way the V4L2 core knows what the capabilities of the
video device are.

But this only really works if all drivers use this, so convert
all radio drivers in this patch.

Subject: media: media/usb: set device_caps in struct video_device

Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.

That way the V4L2 core knows what the capabilities of the
video device are.

But this only really works if all drivers use this, so convert
all usb drivers in this patch.

Subject: media: rtl2832_sdr: set device_caps in struct video_device

Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.

That way the V4L2 core knows what the capabilities of the
video device are.

But this only really works if all drivers use this, so convert
this SDR driver in this patch.

Subject: media: v4l2-mem2mem: add try_en/decoder_cmd ioctl helpers

Most if not all codecs will need to implement these ioctls and
it is expected to be the same for all codecs. So add this to
the core v4l2-mem2mem framework so that this code can easily be
reused.

Subject: media: vimc: Remove or modify stream checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change the way subdevices check if the stream is running. Verify the stream
pointer instead of src_frame. This makes easier to get rid of the void* and
u8* that points to frames in the subdevices structs.

Remove checks that s_stream does on subdevices. They are redundant since
the Media Controller Framework doesn't allow two streaming on the same
media pipeline at the same time.

Subject: media: mtk-vcodec: support single-buffer frames

MT8183 will use a multi-planar format backed by a single buffer. Adapt
the existing code to be able to handle such frames instead of assuming
each frame is backed by two buffers.

Subject: media: vivid: fix incorrect assignment operation when setting video
 mode

The assigment of FB_VMODE_NONINTERLACE to var->vmode should be a
bit-wise or of FB_VMODE_NONINTERLACE instead of an assignment,
otherwise the previous clearing of the FB_VMODE_MASK bits of
var->vmode makes no sense and is redundant.

Addresses-Coverity: ("Unused value")
Fixes: ad4e02d5081d ("[media] vivid: add a simple framebuffer device for overlay testing")

This patch shouldn't have been included in the pull request as it adds
a non-standard raw mode that is for debugging only. So revert
commit ead14a70754f8d7f5dbcb0553c7f11eb0fc4a6ac.

Subject: media: aspeed: refine clock control logic

Currently, this driver calls clk_prepare and clk_unprepare from
interrupt context too but these should be called from sleepable
context only. To fix this issue, this commit splits out
clk_enable/disable and clk_prepare/unprepare, and it places
clk_prepare/unprepare calls into the module probe/remove function.

Subject: media: aspeed: change irq to threaded irq

Differently from other Aspeed drivers, this driver calls clock
control APIs in interrupt context. Since ECLK is coupled with a
reset bit in clk-aspeed module, aspeed_clk_enable will make 10ms of
busy waiting delay for triggering the reset and it will eventually
disturb other drivers' interrupt handling. To fix this issue, this
commit changes this driver's irq to threaded irq so that the delay
can be happened in a thread context.

Subject: media: aspeed: remove IRQF_SHARED flag

Video Engine has a dedicated interrupt line so this driver doesn't
need to use IRQF_SHARED flag so remove it. Also, it'd be good for
following what Thomas recommended in the IRQF_ONESHOT support
patch like below:

"Note that for now IRQF_ONESHOT cannot be used with IRQF_SHARED to
avoid complex accounting mechanisms."

Subject: media: aspeed: reduce noisy log printing outs

Currently, this driver prints out too much log messages when a
mode change happens, video turned off by screen saver and etc.
Actually, all cases are reported to user space properly. Also,
these are not critical errors but recoverable things, so this
commit changes the log level of some noisy printing outs.

Subject: media: aspeed: remove checking of VE_INTERRUPT_CAPTURE_COMPLETE

VE_INTERRUPT_CAPTURE_COMPLETE and VE_INTERRUPT_COMP_COMPLETE are
not set at the same time but the current interrupt handling
mechanism of this driver doesn't clear the interrupt flag until
both two are set, and this behavior causes unnecessary interrupt
handler calls. In fact, this driver provides JPEG format only so
taking care of the VE_INTERRUPT_COMP_COMPLETE is enough for getting
compressed image frame so this commit gets rid of the
VE_INTERRUPT_CAPTURE_COMPLETE checking logic to simplify the logic.
Handling of VE_INTERRUPT_CAPTURE_COMPLETE could be added back later
when it's actually needed.

Subject: media: aspeed: refine interrupt handling logic

There are cases that interrupt bits are cleared by a 500ms delayed
work which causes unnecessary irq calls. Also, the current
interrupt handler returns IRQ_HANDLED always but it should return
IRQ_NONE if there is any unhandled interrupt. So this commit
refines the interrupt handling logic to fix these issues.

Subject: media: v4l2: Fix the _MPLANE format check in v4l_enum_fmt()

CAP_M2M_MPLANE means the device supports _MPLANE formats for both
capture and output. Adjust the check to avoid EINVAL errors on
such devices.

Subject: media: stv6110x: Implement probe/remove for stv6110x

Refactor out the common parts of stv6110x_probe() and stv6110x_attach()
into separate functions.

This provides the needed functionality to use dvb_module_probe() instead
of dvb_attach()!

From 71f49a8bf5c592413edb5c8839ec0e6d754db3e1 Mon Sep 17 00:00:00 2001
From: Sean Young <sean@mess.org>
Date: Tue, 4 Jun 2019 07:19:30 -0400
Subject: media: ttpci: use rc-core for the IR receiver

The IR protocol can now only be set via the rc protocols sysfs file rather
than via module parameters or a custom procfs file. So, it is no longer
necessary to periodically check for protocol changes.

The IR_RCMM protocol does not decode the Philips RC-MM protocol (12, 24 or
32 bit variants) or any protocol rc-core can encode, so this is marked
RC_PROTO_UNKNOWN.

Tested on Technotrend/Hauppauge WinTV Nexus-S rev2.1, which comes
with a small black hauppauge remote.

Subject: media: vicodec: always return a valid format.

Rather than returning width/height values of 0, just default to
a format. Formats in V4L2 are always supposed to be valid, there
is no concept of an invalid format.

Subject: media: vicodec: pass on enc output format to capture side

Setting the encoder output format to e.g. 1920x1080 will set the
crop rectangle to 1920x1088, the coded resolution to 1920x1088 and
the capture coded resolution and sizeimage to 1920x1088 as well.

Note that this might change, since the encoder spec is still in
flux with respect to how this should behave.

Subject: media: vicodec: use correct sizeimage value when draining

After a resolution change is detected, q_data->sizeimage is updated
to the new format, but buf_prepare is still draining buffers that
need to use the old pre-resolution-change value. So store the sizeimage
value in q_data->vb2_sizeimage in queue_setup and use that in
buf_prepare.

Subject: media: vicodec: improve handling of ENC_CMD_STOP/START

Correctly handle stopping and restarting the encoder, keeping
track of the stop and drain states.

In addition it adds correct handling of corner cases, allowing
v4l2-compliance to pass.

Unfortunately, the code is getting to be quite complicated, so
we need to work on better codec support in v4l2-mem2mem.c to
simplify drivers.

Subject: media: uvcvideo: Include streaming interface number in debugfs dir
 name

uvcvideo creates a debugfs directory based on the device bus number and
device number. If a device contains more than one uvc function, the
creation of the second and following debugfs directories will fail and
print an info message like this:
  "uvcvideo: Unable to create debugfs 3-2 directory."

This patch includes the uvc streaming interface number in the debugfs
directory name, to make sure it is unique. The directory name format is
changed from "<busnum>-<devnum>" to "<busnum>-<devnum>-<intfnum>"

Subject: media: fdp1: Support M3N and E3 platforms

New Gen3 R-Car platforms incorporate the FDP1 with an updated version
register. No code change is required to support these targets, but they
will currently report an error stating that the device can not be
identified.

Update the driver to match against the new device types.

Subject: media: drivers: media: i2c: don't enable if CONFIG_DRM_I2C_ADV7511=n

CONFIG_DRM_I2C_ADV7511 and CONFIG_VIDEO_ADV7511 bind to the same
platform device, so whichever driver gets loaded first will be used on
the device. So they shouldn't be enabled at the same time.

Rework so that VIDEO_ADV7511 and VIDEO_COBALT depends on
DRM_I2C_ADV7511=n or COMPILE_TEST.

Subject: media: drivers: media: coda: fix warning same module names

When building with CONFIG_VIDEO_CODA and CONFIG_CODA_FS enabled as
loadable modules, we see the following warning:

  fs/coda/coda.ko
  drivers/media/platform/coda/coda.ko

Rework so media/platform/coda is named coda-vpu. Leaving CODA_FS as is
since that's a well known module.

If vpif_probe() fails on v4l2_device_register() and vpif_probe_complete(),
then memory allocated at initialize_vpif() for global vpif_obj.dev[i]
become unreleased.

The patch adds deallocation of vpif_obj.dev[i] on the error path.

Subject: media: pvrusb2: Add multiple dvb frontend support

All changes are equivalent and backwards compatible.
All current devices have been changed to use fe[0]
Code has been added to dvb init to support cleanup after failure.

Multiple frontends are required by Hauppauge HVR-1975, which is in a
later commit.

Subject: media: stv090x: fix double free on state object

There two callers of stv090x_setup_compound manage the allocation and
freeing if state there is an error condition from stv090x_setup_compound.
Currently function stv090x_setup_compound also frees the state object
too, leading to a double free in the callers of this function.  Fix
this by removing the extraneous free in stv090x_setup_compound and just
leave the callers handle the allocation/free'ing.

Subject: media: v4l2-ctrl: Initialize _BUTTON and _CTRL_CLASS

These two control types don't really need a default value,
as they are not expected to carry any value.

However, it's slightly clearer to initialize them explicitly
instead of falling back to the switch default.

Subject: media: atmel: atmel-isc: split driver into driver base and isc

This splits the Atmel ISC driver into a common base: atmel-isc-base.c
and the driver probe/dt part , atmel-sama5d2-isc.c
This is needed to keep a common ground for the sensor controller which will
be reused.
The atmel-isc will use the common symbols inside the atmel-isc-base
Future driver will also use the same symbols and redefine different aspects,
for a different version of the ISC.
This is done to avoid complete code duplication by creating a totally
different driver for the new variant of the ISC.

Subject: media: i2c: fix warning same module names

When building with CONFIG_VIDEO_ADV7511 and CONFIG_DRM_I2C_ADV7511
enabled as loadable modules, we see the following warning:

  drivers/gpu/drm/bridge/adv7511/adv7511.ko
  drivers/media/i2c/adv7511.ko

Rework so that the file is named adv7511-v4l2.c.

Subject: media: rcar-vin: Do not call pm_runtime_{resume,suspend}()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver does not implement runtime resume and suspend function so
there is little point in trying to call them. This is a leftover from
the drivers soc_camera beginnings.

Subject: media: rcar-vin: Remove unneeded calls to pm_runtime_{enable,
 disable}
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Runtime PM is already enabled unconditionally when the driver is probed
and disabled when it's removed. There is no point in doing it again for
Gen2 when opening and closing the video device.

The helpers rvin_power_{on,off} deal with both VIN and the parallel
subdevice power. This makes it hard to merge the Gen2 and Gen3
open/release functions. Move the VIN power handling directly to the
open/release functions to prepare for the merge.

Subject: media: s5p-mfc: Make additional clocks optional

Since the beginning the second clock ('special', 'sclk') was optional and
it is not available on some variants of Exynos SoCs (i.e. Exynos5420 with
v7 of MFC hardware).

However commit 1bce6fb3edf1 ("[media] s5p-mfc: Rework clock handling")
made handling of all specified clocks mandatory. This patch restores
original behavior of the driver and fixes its operation on
Exynos5420 SoCs.

Fixes: 1bce6fb3edf1 ("[media] s5p-mfc: Rework clock handling")

Subject: media: vimc: Makefile: file cleanup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove redundant Makefile rules (vimc_capture-objs, ...).

Stop exposing vimc-{common, streamer} as modules, since there's no use
case where they would be individually added/removed from Vimc. As
consequence, remove MODULE_ macros from vimc-{common, streamer}.

`-objs` is fitted for building host programs, change to `-y`, more
straightforward for device drivers.

Subject: media: mtk-vcodec: avoid unneeded pointer-to-long conversions

The interface used to communicate with the firmware casts pointers
into unsigned longs and back again in order to store private
references, all of this for pointers that remain purely in the kernel.
Replace these unsigned longs with void pointers to make the code a bit
sturdier and easier to follow.

Also simplify some interfaces by removing arguments that could be
infered from others.

Subject: media: mtk-vcodec: remove unneeded proxy functions

We were getting the codec interface through a proxy function that does
not bring anything compared to just accessing the interface definition
directly, so just do that. Also make the decoder interfaces const.

Subject: media: vivid: remove unnecessary min and max timeperframe constants

The tpf_min (1/100) and tpf_max (100/1) are used as the lowest and the
highest allowable value for the desired frame period in
vivid_vid_cap_s_parm().

But the comparison between these values is unnecessary because the compared
value is already chosen from webcam_intervals[] (from 1/60 to 1/1).

Subject: media: aspeed: add a workaround to fix a silicon bug

AST2500 silicon revision A1 and A2 have a silicon bug which causes
extremly long capturing time on specific resolutions (1680 width).
To fix the bug, this commit adjusts the capturing window register
setting to 1728 if detected width is 1680. The compression window
register setting will be kept as the original width so output
result will be the same.

Subject: media: vivid: make input dv_timings per-input

Make the following properties per-input

-DV Timings Signal Mode
-DV Timings

These properties need to be per-input in order to implement proper
HDMI (dis)connect-behavior, where the signal mode will be used to
signify whether or not there is an input device connected.

Subject: media: vivid: make input std_signal per-input

Make the following properties per-input:

-Standard Signal Mode
-Standard

These properties need to be per-input in order to implement proper HDMI
(dis)connect-behavior, where the signal mode will be used to signify
whether or not there is an inpute device connected.

Adds the following bitmask controls:
-V4L2_CID_DV_TX_EDID_PRESENT
-V4L2_CID_DV_TX_HOTPLUG
-V4L2_CID_DV_TX_RXSENSE

The bitmasks are all set based on the custom vivid DISPLAY_PRESENT
control. This also removes 2/2 v4l2-compliance warnings for vivid
output device.

Subject: media: vivid: reorder CEC allocation and control set-up

CEC adapters and controllers (handlers) are now set up as follows:

1. Allocate CEC adapters: setup of control handlers in next step
   requires these adapters to be allocated.
2. Setup of control handlers: This must be done prior to registering
   and exposing the adapters to user space to avoid a race condition.
3. Register CEC adapters: make them available to user space.

Subject: media: ov6650: Fix device node exposed without proper locking

Commit c62b96050bee ("media: ov6650: Register with asynchronous
subdevice framework") carelessly requested creation of a video device
node by setting a V4L2_SUBDEV_FL_HAS_DEVNODE flag.  The driver is not
ready for that as it doesn't implement proper locking required for
serialization of IOCTLs.

Fix it by dropping the flag assignment.

PTR_ERR(NULL) yields 0 which is commonly used to denote success. This is
the case here, and PTR_ERR(NULL) is apparently shunned upon. Fix this by

devm_gpiod_get never returns NULL; therefore it's not necessary to check

Subject: media: mt9m111: add regulator support

In the soc_camera removal, the board specific power callback was
dropped. This at least will remove the power optimization from ezx and
em-x270 pxa based boards.

As to recreate the same level of functionality, make the mt9m111 have a
regulator providing it its power, so that board designers can plug in a
gpio based or ldo regulator, mimicking their former soc_camera power
hook.

Subject: media: mt9m111: No need to check for the regulator

The regulator_get() function returns a regulator when it succeeds. There's
no need to check whether the regulator is NULL later on.

In the patch refactoring the fw-node, the mt9m111 was broken for all
platform_data based platforms, which were the first aim of this
driver. Only the devicetree platform are still functional, probably
because the testing was done on these.

The result is that -EINVAL is systematically return for such platforms,
what this patch fixes.

Subject: media: Revert "[media] marvell-ccic: reset ccic phy when stop
 streaming for stability"

This accesses the clock registers directly and thus is going to stay in the
way of making the driver devicetree friendly.

No boards seems to actually use this. If it's somehow actually needed it
needs to be done differently.

This reverts commit 7c269f454e7a51b151d94f99344120efa1cd0acb.

Use the names more suitable for devicetree bindings.

There are no board files utilizing this, thus we seem to be at liberty
at renaming this without consequences.

Subject: media: marvell-ccic: use async notifier to get the sensor

An instance of a sensor on DT-based MMP2 platform is always going to be
created asynchronously.

Let's move the manual device creation away from the core to the Cafe
driver (used on OLPC XO-1, not present in DT) and set up appropriate
async matches: I2C on Cafe, FWNODE on MMP (OLPC XO-1.75).

From 81a409bfd5517d537097d3cfdfed7f8bf8ac469c Mon Sep 17 00:00:00 2001
From: Lubomir Rintel <lkundrak@v3.sk>
Date: Tue, 28 May 2019 05:07:31 -0400
Subject: media: marvell-ccic: provide a clock for the sensor

The sensor needs the MCLK clock running when it's being probed. On
platforms where the sensor is instantiated from a DT (MMP2) it is going
to happen asynchronously.

Therefore, the current modus operandi, where the bridge driver fiddles
with the sensor power and clock itself is not going to fly. As the comments
wisely note, this doesn't even belong there.

Luckily, the ov7670 driver is already able to control its power and
reset lines, we can just drop the MMP platform glue altogether.

It also requests the clock via the standard clock subsystem. Good -- let's
set up a clock instance so that the sensor can ask us to enable the clock.
Note that this is pretty dumb at the moment: the clock is hardwired to a
particular frequency and parent. It was always the case.

Subject: media: st-mipid02: add support of V4L2_CID_LINK_FREQ

Ask device connected on sink pad for link frequency
in order to configure CLK_LANE_REG1 (ui_x4).
If not available, ask for pixel rate information to compute it.

This is needed to deal with compressed format such as JPEG
where number of bits per pixel is unknown: computation of
link frequency from pixel rate is not possible.

Avoid pointlessly calling calc_dphy() when the bus is not
V4L2_MBUS_CSI2_DPHY. This will make it easier to replace the platform data
with devicetree.

Subject: media: coda: fix last buffer handling in V4L2_ENC_CMD_STOP

coda_encoder_cmd() is racy, as the last scheduled picture run worker can
still be in-flight while the ENC_CMD_STOP command is issued. Depending
on the exact timing the sequence numbers might already be changed, but
the last buffer might not have been put on the destination queue yet.

In this case the current implementation would prematurely wake the
destination queue with last_buffer_dequeued=true, causing userspace to
call streamoff before the last buffer is handled.

Close this race window by synchronizing with the pic_run_worker before
doing the sequence check.

Subject: media: coda: fix V4L2_DEC_CMD_STOP when all buffers are already
 consumed

When the DEC_CMD_STOP command is issued after the context has already
consumed all the queued buffers, we need to make sure to wake the
destination queue with last_buffer_dequeued set, to allow userspace to
make progress in its EOS handling.

As there might still be picture run workers pending at that point, we
need to synchronize with them, so the sequence number comparison reads
stable values.

Subject: media: coda: split decoder sequence initialization out of start
 decoding

The sequence initialization already has to happen during the
initialization phase, after headers have been queued on the OUTPUT
queue. This means that sequence initialization has to be queued as
a work item from QBUF on the OUTPUT queue. The internal framebuffer
setup should be done later during VIDIOC_REQBUFS() on the CAPTURE
queue.

Pass vaddr and size to coda_bitstream_queue instead of a struct
vb2_v4l2_buffer to make it reusable for queueing data that is
not exactly a whole v4l2 buffer into the bitstream ringbuffer.

Subject: media: coda: pad first buffer with repeated MPEG headers to fix
 sequence init

If the first buffer contains only headers, the sequence initialization
command fails. On CodaHx4 the buffer must be padded to at least 512
bytes, on CODA960 it seems to be enough to just repeat the sequence and
extension headers (MPEG-2) or the VOS and VO headers (MPEG-4) once for
for sequence initialization to succeed without further bitstream data.
On CodaHx4 the headers can be repeated multiple times until the 512 byte
mark is reached.

A similar issue was solved for h.264 by padding with a filler NAL in
commit 0eef89403ece ("[media] coda: pad first h.264 buffer to 512
bytes").

On CODA960, sequence initialization can succeed if less than 512 bytes
are ready in the bitstream ring buffer.
On other variants, warn about too small payload in start_streaming.

Subject: media: coda: flush bitstream ring buffer on decoder restart

The bitstream ringbuffer might be in an underrun state after draining,
or it might still contain unread data if the previous decoder stop
command was flagged as immediate. Flush the bitstream ring buffer
during V4L2_DEC_CMD_START to get into a well defined state. Also fill
the bitstream with buffers that have been queued during draining,
to resume decoding immediately.

If no more frames are decoded in bitstream end mode, and a previously

increment the sequence_offset correction parameter.

Subject: media: coda: only set the stream end flags if there are no more
 pending output buffers

If there are still queued output buffers pending to be copied into the
bitstream ring buffer, setting the stream end flag should be deferred
until the marked last output buffer is written into the bitstream ring
buffer.

Using the output queue sequence counter to determine the last buffer to
be encoded or decoded always was fragile at best. Now that we have the
last buffer flag propagating from the output queue to the capture queue
correctly, this is not needed anymore.

Subject: media: coda: only wake up capture queue if no pending buffers to

If there are no pending queued output buffers to be encoded, waking up
the capture queue with -EPIPE signals end of stream. If there are
pending buffers on the other hand, setting the V4L2_BUF_FLAG_LAST on
the resulting encoded capture buffers is all that is needed.

If there is still a buffer pending, mark it as the last buffer. It will
create a meta that is flagged as last when the buffer is copied into the
bitstream ring buffer. If there are no more buffers pending, find the
last bitstream meta and mark it as last. If there is no bitstream meta
either, wake up the capture queue as there will be no more decoded
frames.

If reordering is not enabled, the last decoded frame has to be the last
returned buffer. Otherwise wait for the firmware to report no more
frame to display. In that case the return buffer is the last one as
well, and can be reported as such.

Subject: media: coda: store device pointer in driver structure instead of pdev

only to convert it into a device pointer wherever it is used. Just
store the device pointer directly.

From a8fa55078a7784a99a2ce389b5d7456a3be9a941 Mon Sep 17 00:00:00 2001

Subject: media: v4l2-subdev: Verify arguments in v4l2_subdev_call()

Correctness of format type (try or active) and pad number parameters
passed to subdevice operation callbacks is now verified only for IOCTL
calls.  However, those callbacks are also used by drivers, e.g., V4L2
host interfaces.

Since both subdev_do_ioctl() and drivers are using v4l2_subdev_call()
macro while calling subdevice operations, move those parameter checks
from subdev_do_ioctl() to v4l2_subdev_call() so we can avoid taking care
of those checks inside drivers.

Define a wrapper function for each operation callback in scope, then
gather those wrappers in a static v4l2_subdev_ops structure so the
v4l2_subdev_call() macro can find them easy if provided.

Subject: media: v4l2-subdev: Verify v4l2_subdev_call() pad config argument

Extend parameter checks performed by v4l2_subdev_call() with a check for
a non-NULL pad config pointer if V4L2_SUBDEV_FORMAT_TRY format type is
requested so drivers don't need to care.

Subject: media: media/pci: set device_caps in struct video_device

Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.

That way the V4L2 core knows what the capabilities of the
video device are.

But this only really works if all drivers use this, so convert
all pci drivers in this patch.

Tested with cx88-blackbird and ivtv PVR-350.

Subject: media: vimc: cap: check v4l2_fill_pixfmt return value
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

v4l2_fill_pixfmt() returns -EINVAL if the pixelformat used as parameter is
invalid or if the user is trying to use a multiplanar format with the
singleplanar API. Currently, the vimc_cap_try_fmt_vid_cap() returns such
value, but vimc_cap_s_fmt_vid_cap() is ignoring it. Fix that and returns
an error value if vimc_cap_try_fmt_vid_cap() has failed.

Rework std_init adding an explicit initialization for
compound controls.

While here, make sure the control is initialized to zero,
before providing default values for all its fields.

cfg->type can be overridden by v4l2_ctrl_fill() and the new value is
stored in the local type var. Fix the tests to use this local var.

Subject: media: hdpvr: fix locking and a missing msleep

This driver has three locking issues:

- The wait_event_interruptible() condition calls hdpvr_get_next_buffer(dev)
  which uses a mutex, which is not allowed. Rewrite with list_empty_careful()
  that doesn't need locking.

- In hdpvr_read() the call to hdpvr_stop_streaming() didn't lock io_mutex,
  but it should have since stop_streaming expects that.

- In hdpvr_device_release() io_mutex was locked when calling flush_work(),
  but there it shouldn't take that mutex since the work done by flush_work()
  also wants to lock that mutex.

There are also two other changes (suggested by Keith):

- msecs_to_jiffies(4000); (a NOP) should have been msleep(4000).
- Change v4l2_dbg to v4l2_info to always log if streaming had to be restarted.

Subject: media: cec: add struct cec_connector_info support

Define struct cec_connector_info in media/cec.h and define
CEC_CAP_CONNECTOR_INFO. In a later patch this will be moved to
uapi/linux/cec.h.

The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but
cec_allocate_adapter() will remove it again until the public API
for this can be enabled once all drm drivers wire this up correctly.

Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions,
which are needed by drm drivers to fill in the cec_connector info
based on a drm_connector.

The cec_notifier_(un)register and cec_register_cec_notifier
prototypes were moved from cec-notifier.h to cec.h since cec.h no longer
includes cec-notifier.h. These headers included each other before,
which caused various problems.

Due to these changes the seco-cec driver was changed as well: it
should include cec-notifier.h, not cec.h.

Subject: media: cec-notifier: add new notifier functions

In order to support multiple CEC devices for an HDMI connector,
and to support cec_connector_info, drivers should use either a
cec_notifier_conn_(un)register pair of functions (HDMI drivers)
or a cec_notifier_cec_adap_(un)register pair (CEC adapter drivers).

This replaces cec_notifier_get_conn/cec_notifier_put.

For CEC adapters it is also no longer needed to call cec_notifier_register,
cec_register_cec_notifier and cec_notifier_unregister. This is now
all handled internally by the new functions.

Subject: media: dvb_frontend: split dvb_frontend_handle_ioctl function

Over time, dvb_frontend_handle_ioctl() has grown to the point where
we now get a warning from the compiler about excessive stack usage:

drivers/media/dvb-core/dvb_frontend.c: In function 'dvb_frontend_handle_ioctl':
drivers/media/dvb-core/dvb_frontend.c:2692:1: error: the frame size of 1048 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

Almost all of this is used by the dtv_frontend_properties structure
in the FE_GET_PROPERTY and FE_GET_FRONTEND commands. Splitting those
into separate function reduces the stack usage of the main function
to just 136 bytes, the others are under 500 each.

Subject: media: rc: Prefer KEY_NUMERIC_* for number buttons on remotes

Prefer KEY_NUMERIC_* for number buttons on remotes. Now all the remotes
use KEY_NUMERIC_[0-9] for the number buttons rather than keys that
could be affected by modifiers (Caps-Lock, or Num-Lock) or regional
keymaps.

Created using:
sed -i  's/KEY_\([0-9]\) /KEY_NUMERIC_\1 /' *.c
sed -i  's/KEY_\([0-9]\)}/KEY_NUMERIC_\1}/' *.c
sed -i  's/``KEY_\([0-9]\)/``KEY_NUMERIC_\1/' Documentation/media/uapi/rc/rc-tables.rst

Subject: media: stv0297: fix frequency range limit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There was a typo at the lower frequency limit for a DVB-C
card, causing the driver to fail while tuning channels at the
VHF range.

Subject: media: radio-raremono: change devm_k*alloc to k*alloc

Change devm_k*alloc to k*alloc to manually allocate memory

The manual allocation and freeing of memory is necessary because when
the USB radio is disconnected, the memory associated with devm_k*alloc
is freed. Meaning if we still have unresolved references to the radio
device, then we get use-after-free errors.

This patch fixes this by manually allocating memory, and freeing it in
the v4l2.release callback that gets called when the last radio device
exits.
