I observed the following problem with the BT404 touch pad
running the Phosh UI:
When e.g. typing on the virtual keyboard pressing "g" would
produce "ggg".
After some analysis it turns out the firmware reports that three
fingers hit that coordinate at the same time, finger 0, 2 and
4 (of the five available 0,1,2,3,4).
DOWN
Zinitix-TS 3-0020: finger 0 down (246, 395)
Zinitix-TS 3-0020: finger 1 up (0, 0)
Zinitix-TS 3-0020: finger 2 down (246, 395)
Zinitix-TS 3-0020: finger 3 up (0, 0)
Zinitix-TS 3-0020: finger 4 down (246, 395)
UP
Zinitix-TS 3-0020: finger 0 up (246, 395)
Zinitix-TS 3-0020: finger 2 up (246, 395)
Zinitix-TS 3-0020: finger 4 up (246, 395)
This is one touch and release: i.e. this is all reported on
touch (down) and release.
There is a field in the struct touch_event called finger_cnt
which is actually a bitmask of the fingers active in the
event.
Rename this field finger_mask as this matches the use contents
better, then use for_each_set_bit() to iterate over just the
fingers that are actally active.
Factor out a finger reporting function zinitix_report_fingers()
to handle all fingers.
Also be more careful in reporting finger down/up: we were
reporting every event with input_mt_report_slot_state(..., true);
but this should only be reported on finger down or move,
not on finger up, so also add code to check p->sub_status
to see what is happening and report correctly.
After this my Zinitix BT404 touchscreen report fingers
flawlessly.
The vendor drive I have notably does not use the "finger_cnt"
and contains obviously incorrect code like this:
if (touch_dev->touch_info.finger_cnt > MAX_SUPPORTED_FINGER_NUM)
touch_dev->touch_info.finger_cnt = MAX_SUPPORTED_FINGER_NUM;
As MAX_SUPPORTED_FINGER_NUM is an ordinal and the field is
a bitmask this seems quite confused.

In preparation for SMMUv2 PMU support, rejig our IRQ setup code to
account for PMU interrupts as additional resources. We can simplify the
whole flow by only storing the context IRQs, since the global IRQs are
devres-managed and we never refer to them beyond the initial request.

Since the block layer doesn't support variable length reference tags,
driver support for the Storage Tag space is not supported at this time.

The block integrity subsystem knows how to construct protection
information buffers with metadata beyond the protection information
fields. Remove the driver restriction.
Note, this can only work if the PI field appears first in the metadata,
as the integrity subsystem doesn't calculate guard tags on preceding
metadata.

Pull MTD fix from Miquel Raynal:
"As part of a previous changeset introducing support for the K3
architecture, the OMAP_GPMC (a non visible symbol) got selected by the
selection of MTD_NAND_OMAP2 instead of doing so from the architecture
directly (like for the other users of these two drivers). Indeed, from
a hardware perspective, the OMAP NAND controller needs the GPMC to
work.
This led to a robot error which got addressed in fix merge into -rc4.
Unfortunately, the approach at this time still used "select" and lead
to further build error reports (sparc64:allmodconfig).
This time we switch to 'depends on' in order to prevent random
misconfigurations. The different dependencies will however need a
future cleanup"

With FEAT_ECV and the 1GHz counter, it is pretty likely that the
event stream divider doesn't fit in the field that holds the
divider value (we only have 4 bits to describe counter bits [15:0]
Thankfully, FEAT_ECV also provides a scaling mechanism to switch
the field to cover counter bits [23:8] instead.
Enable this on arm64 when ECV is available (32bit doesn't have
any detection infrastructure and is unlikely to be run on an
ARMv8.6 system anyway).

The driver statically defines maximum number of interrupts it can
handle, however it does not respect that limit when configuring them.
When provided with a DTS with more interrupts than assumed, the driver
will overwrite static array mct_irqs leading to silent memory
corruption.
Validate the interrupts coming from DTS to avoid this. This does not
change the fact that such DTS might not boot at all, because it is
simply incompatible, however at least some warning will be printed.

The existing fix for errata i940 causes a conflict for IPU2 which is
using timer 3 and 4. From arch/arm/boot/dts/dra7-ipu-dsp-common.dtsi:
&ipu2 {
mboxes = <&mailbox6 &mbox_ipu2_ipc3x>;
ti,timers = <&timer3>;
ti,watchdog-timers = <&timer4>, <&timer9>;
};
The conflict was noticed when booting mainline on the BeagleBoard X15
which has a TI AM5728 SoC:
remoteproc remoteproc1: 55020000.ipu is available
remoteproc remoteproc1: powering up 55020000.ipu
remoteproc remoteproc1: Booting fw image dra7-ipu2-fw.xem4
omap-rproc 55020000.ipu: could not get timer platform device
omap-rproc 55020000.ipu: omap_rproc_enable_timers failed: -19
remoteproc remoteproc1: can't start rproc 55020000.ipu: -19
This change modifies the errata fix to instead use timer 15 and 16 which
resolves the timer conflict.
It does not appear to introduce any latency regression. Results from
cyclictest with original errata fix using dmtimer 3 and 4:
# cyclictest --mlockall --smp --priority=80 --interval=200 --distance=0

The root of the problem is that we are selecting symbols that have

The cleanest solution is to avoid using select.

The VIDIOC_G_FBUF and related overlay ioctls no longer worked (-ENOTTY was
returned).
The root cause was the introduction of the caps field in ivtv-driver.h.
While loading the ivtvfb module would update the video_device device_caps
field with V4L2_CAP_VIDEO_OUTPUT_OVERLAY it would not update that caps
field, and that's what the overlay ioctls would look at.
It's a bad idea to keep information in two places, so drop the caps field

It does not make sense to have a comma after a sentinel, as any new
elements must be added before the sentinel.

'dev' will *always* be set by list_for_each_entry().
It is incorrect to assume that the iterator value will be NULL if the
list is empty.
Instead of checking the pointer it should be checked if
the list is empty.

The max2175 uses a flat register cache but supplies only a single default
value and has many volatile registers. This is a poor fit for a flat cache
since the cache will assume a default of zero for any register not yet
written which can lead to bugs for example when regmap_update_bits()
suppresses a noop write. A rbtree cache is a much better fit, this will
only cache default values and values that have been written to the device
with any reads of uncached values going to the hardware. Convert the driver
to use a rbtree cache.
Since the device is controlled via I2C the cost of manging the rbtree
should be immaterial compared to the cost of accessing the device.
