Both callers of __atomisp_css_recover() check atomisp_streaming_count()
first, move the check into __atomisp_css_recover().
And __atomisp_css_recover() already calls lockdep_assert_held(&isp->mutex),
so drop that from atomisp_css_flush().

The watchdog timer code to recover from the ISP getting stuck has several
major issues:
1. There is no way to do fault injection and normally the ISP does not
get stuck, so is it is impossible to test it.
2. It in essence just stops all streams, resets the ISP and then brings
everything back up. Userspace can easily do this itself by using a
timeout on dqbuf and then closing (which causes a poweroff) +
re-opening the device. Doing this in userspace (if it ever turns out
to be necessary) greatly simplifies the kernel code and in general
will be a more robust solution.
Even just a quick look at the code finds several more issues:
3. The need to sync-cancel the timers + work on streamoff requires
isp->mutex to be dropped halfway during the ioctl opening all sorts of
races.
4. The atomisp code supports setting up 2 pipelines, streaming from
two sensors at the same time. But there is only a single wdt_work
and stopping one of the 2 streams will cancel the timers + work,
stopping the wdt even though the other stream might still be running.
5. In case atomisp_css_flush() the sync cancel is done while keeping
isp->mutex locked, causing a deadlock when racing with wdt_work which
also takes isp->mutex.
6. Even though the watchdog is purely a software/driver thing which
just checkes that new frames keep coming in, there are 2 completely
different implementations for the ISP2400/ISP2401 which is not
necessary at all.
So all in all I believe that it is better to just remove the current
watchdog implementation. Fixing all the issues with the current
implementation will be so much work, that if it turns out that we do
need something like this then doing a clean re-implementation from
scratch will be better anyways.
wdt_work was also (ab)used to reset the ISP after the firmware signalled
an fw-assert error through the irq, add a new assert_recover_work to
replace this.

Several of the ioctl handlers all do the same checks
(isp->fatal_error and asd->streaming errors) add
an atomisp_pipe_check() helper for this.
Note this changes the vidioc_s_fmt_vid_cap and vidioc_s_input handlers
to now reject calls made while asd->streaming==STOPPING. This fixes
a possible race where one thread can make this ioctls while
vidioc_streamoff is running from another thread and it has
temporarily released isp->mutex to kill the watchdog timers / work.

At probe time isp_subdev_init_entities() sets pipe->asd to a non NULL
value for all four (preview/vf/capture/capture_video) pipes by calling
atomisp_init_subdev_pipe() for all 4 pipes.
So it can never be NULL. Remove the redundant NULL checks.

For reading / writing the asd->streaming enum the following rules
should be followed:
1. Writers of streaming must hold both isp->mutex and isp->lock.
2. Readers of streaming need to hold only one of the two locks.
Not all writers where properly taking both locks this fixes this.
In the case of the readers, many readers depend on their caller
to hold isp->mutex, add asserts for this
And in the case of atomisp_css_get_dis_stat() it is called with
isp->mutex held, so there is no need to take the spinlock just
for reading the streaming value.

There is no reason for atomisp to use a rt_mutex instead of a normal
mutex, so switch over to a normal mutex.
All the changes in this patch are just s/rt_mutex/mutex/.
This is a preparation patch for switching the ioctl locking over
to using the video_dev.lock member so that the v4l2-core takes
care of the locking.

The ACC /dev/video# device node uses a struct video_device embedded in
an atomisp_acc_pipe struct instead of in an atomisp_video_pipe struct.
Yet it uses the same file-ops and ioctl-ops even though it does not have
a videobuf queue, which makes e.g. the mmap fop nonsense.
Worse the only file-ops / ioctls which differentiate between
the 2 types and correctly do container_of on the right type
are the open/release fops and the vidioc_default handler.
The mmap and poll fops and *all* other ioctl handlers unconditionally
do container_of on the passed in struct video_device blindly assuming
they are dealing with the one embedded in the atomisp_video_pipe struct.
This makes it trivial for userspace to cause all sort of undefined behavior
by calling mmap, poll or the other ioctls on the ACC device node!
Presumably the use of the ACC device node was to allow making the special
ioctls to load custom programs while the other /dev/video# nodes were
already open, since the /dev/video# nodes can currently all be opened
only once (which needs to be fixed).
commit 4bbca788b6eb ("media: atomisp: remove private acceleration ioctls")
has removed the custom ATOMISP_ACC_* ioctls, so there no longer is any
reason to keep the ACC device node.
As explained above its presence can easily cause the kernel to crash,
so remove the ACC device node and the code for handling it.

atomisp_try_fmt() gives results with padding included. So when userspace
asks for e.g. 1600x1200 then we should pass 1616x1216 to atomisp_try_fmt()
this will then get adjusted back to 1600x1200 before returning it to
userspace by the atomisp_adjust_fmt() call at the end of atomisp_try_fmt().
This fixes the resolution list in camorama showing resolutions like e.g.
1584x1184 instead of 1600x1200.

atomisp_try_fmt() calls the sensor's try_fmt handler but it does
not copy the result back to the passed in v4l2_pix_format under
some circumstances.
Potentially returning an unsupported resolution to userspace,
which VIDIOC_TRY_FMT is not supposed to do.
atomisp_set_fmt() also uses atomisp_try_fmt() and relies
on this wrong behavior. The VIDIOC_TRY_FMT call passes NULL for
the res_overflow argument where as the atomisp_set_fmt() call
passes non NULL.
Use the res_overflow argument to differentiate between the 2 callers
and always propagate the sensors result in the VIDIOC_TRY_FMT case.
This fixes the resolution list in camorama showing resolutions like e.g.
1584x1184 instead of 1600x1200.

On sets actually store the set (closest) format inside ov2680_device.dev,
so that it also properly gets returned by get_fmt.
This fixes the following problem:
1. App does an VIDIOC_SET_FMT 640x480, calling ov2680_set_fmt()
2. Internal buffers (atomisp_create_pipes_stream()) get allocated
at 640x480 size by atomisp_set_fmt()
3. ov2680_get_fmt() gets called later on and returns 1600x1200
since ov2680_device.dev was not updated. So things get configured
to stream at 1600x1200, but the internal buffers created during
atomisp_create_pipes_stream() do not get updated in size
4. streaming starts, internal buffers overflow and the entire
machine freezes eventually due to memory being corrupted

1st set of IIO new device support, features and cleanup for 6.1
This includes Nuno Sa's work to move the IIO core over to generic firmware
properties rather than having DT specific code paths. Combined with Andy
Shevchenko's long term work on drivers, this leaves IIO in a good state for
handling other firmware types.
New device support
- liteon,ltrf216a
* New driver and dt bindings to support this Light sensor.
- maxim,max11205
* New driver for this 16bit single channel ADC.
- memsensing,msa311
* New driver for this accelerometer. Includes a string helper for read/write.
- richtek,rtq6056
* New driver and dt binding to support this current monitor used to measure
power usage.
- yamaha,yas530
* Support the YAS537 variant (series includes several fixes for other parts
and new driver features).
Staging graduation
- adi,ad7746 CDC. Cleanup conducted against set of roadtest tests using
the posted RFC of that framework.
Features
- core
* Large rework to make all the core IIO code use generic firmware properties.
Includes switching some drivers over as well using newly provided
generic interfaces and allowing removal of DT specific ones.
* Support for gesture event types for single and double tap. Used in
bosch,bma400.
- atmel,at91-sama5d2
* Add support for temperature sensor which uses two muxed inputs to estimate
the temperature.
* Handle trackx bits of EMR register to improve temp sampling accuracy.
* Runtime PM support.
- liteon,ltrf216a
* Add a _raw channel output to allow working around an issue with
differing conversions equations that breaks some user space controls.
- mexelis,mlx90632
* Support regulator control.
- ti,tsc2046
* External reference voltage support.
Clean up and minor fixes
- Tree-wide
* devm_clk_get_enabled() replacements of opencoded equivalent.
* Remaining IIO_DMA_MINALIGN conversions (the staging/iio drivers).
* Various minor warning and similar cleanup such as missing static
markings.
* strlcpy() to strscpy() for cases where return value not checked.
* provide units.h entries for more HZ units and use them in drivers.
- dt-bindings cleanup
* Drop maintainers listss where the email address is bouncing.
* Switch spi devices over to using spi-peripheral.yaml
* Add some missing unevaluatedProperties / additionalProperties: false
entries.
- ABI docs
* Add some missing channel type specific sampling frequency entries.
* Add parameter names for callback parameters.
- MAINTAINERS
* Fix wrong ADI forum links.
- core
* lockdep class per device, to avoid an issue with nest when one IIO
device is the consumer of another.
* White space tweaks.
- asc,dlhl60d
* Use get_unaligned_be24 to avoid some unusual data manipulation and masking.
- atmel,at91-sama5d2
* Fix wrong max value.
* Improve error handling when measuring pressure and touch.
* Add locks to remove races on updating oversampling / sampling freq.
* Add missing calls in suspend and resume path to ensure state is correctly
brought up if buffered capture was in use when suspend happened.
* Error out of write_raw() callback if buffered capture enabled to avoid
unpredictable behavior.
* Handle different versions having different oversampling ratio support and
drop excess error checking.
* Cleanup magic value defines where the name is just the value and hence
hurts readability.
* Use read_avail() callback to provide info on possible oversampling ratios.
* Correctly handle variable bit depth when doing oversampling on different
supported parts. Also handle higher oversampling ratios.
- fsl,imx8qxp
* Don't ignore errors from regulator_get_voltage() so as to avoid some
very surprising scaling.
- invensense,icp10100
* Switch from UNIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS. UNIVERSAL rarely made
sense and is now deprecated. In this driver we just avoid double disabling
in some paths.
- maxim,max1363
* Drop consumer channel map provision by platform data. There have been
better ways of doing this for years and there are no in tree users.
- microchip,mcp3911
* Update status to maintained.
- qcom,spmi-adc5
* Support measurement of LDO output voltage.
- qcom,spmi-adc
* Add missing channel available on SM6125 SoC.
