This converts the Zinitix BT4xx and BT5xx touchscreen bindings to YAML,
fix them up a bit and extends them.
We list all the existing BT4xx and BT5xx components with compatible
strings. These are all similar, use the same bindings and work in
similar ways.
We rename the supplies from the erroneous vdd/vddo to the actual supply
names vcca/vdd as specified on the actual component. It is long
established that supplies shall be named after the supply pin names of a
component. The confusion probably stems from that in a certain product
the rails to the component were named vdd/vddo. Drop some notes on how OS
implementations should avoid confusion by first looking for vddo, and if
that exists assume the legacy binding pair and otherwise use vcca/vdd.
Add reset-gpios as sometimes manufacturers pulls a GPIO line to the reset
line on the chip.
Add optional touchscreen-fuzz-x and touchscreen-fuzz-y properties.

The power button on Cherry Trail systems with an AXP288 PMIC is connected
to both the power button pin of the PMIC as well as to a power button GPIO
on the Cherry Trail SoC itself. This leads to double power button event
reporting which is a problem.
Since reporting power button presses through the PMIC is not supported on
all PMICs used on Cherry Trail systems, we want to keep the GPIO
power button events, so the axp20x-pek code checks for the presence of
a GPIO power button and in that case does not register its input-device.
On most systems the GPIO power button also can wake-up the system from
suspend, so the axp20x-pek driver would also not register its interrupt
handler. But on some systems there was a bug causing wakeup by the GPIO
power button handler to not work.
Commit 9747070c11d6 ("Input: axp20x-pek - always register interrupt
handlers") was added as a work around for this registering the axp20x-pek
interrupts, but not the input-device on Cherry Trail systems.
In the mean time the root-cause of the GPIO power button wakeup events
not working has been found and fixed by the "pinctrl: cherryview: Do not
allow the same interrupt line to be used by 2 pins" patch,
so this is no longer necessary.
This reverts the workaround going back to only registering the
interrupt handlers on systems where we also register the input-device.

The open delay time has to be applied only on the first sample of the
X/Y coordinates because on the following samples the ADC channel is not
changed. Removing this time from the samples after the first one,
"ti,coordinate-readouts" greater than 1, decreases the total acquisition
time, allowing to increase the number of acquired coordinates in the time
unit.

Some Silead touchscreens have support for an active (battery powered)
pen, add support for this.
So far pen-support has only been seen on X86/ACPI (non devicetree) devs,
IOW it is not used in actual devicetree files. The devicetree-bindings
maintainers have requested properties like these to not be added to the
devicetree-bindings, so the new properties are deliberately not added
to the existing silead devicetree-bindings documentation.

coordinates
Unfortunately, at the time of writing this commit message, we have been
unable to get permission from Silead, or from device OEMs, to distribute
the necessary Silead firmware files in linux-firmware.
On a whole bunch of devices the UEFI BIOS code contains a touchscreen
driver, which contains an embedded copy of the firmware. The fw-loader
code has a "platform" fallback mechanism, which together with info on the
firmware from drivers/platform/x86/touchscreen_dmi.c will use the firmware
from the UEFI driver when the firmware is missing from /lib/firmware. This
makes the touchscreen work OOTB without users needing to manually download
the firmware.
The firmware bundled with the original Windows/Android is usually newer
then the firmware in the UEFI driver and it is better calibrated. This
better calibration can lead to significant differences in the reported
min/max coordinates.
Add support for a new (optional) "silead,efi-fw-min-max" property which
provides a set of alternative min/max values to use for the x/y axis when
the EFI embedded firmware is used.
The new property is only used on (x86) devices which do not use devicetree,
IOW it is not used in actual devicetree files. The devicetree-bindings
maintainers have requested properties like these to not be added to the
devicetree-bindings, so the new property is deliberately not added to the
existing silead devicetree-bindings documentation.

Some Goodix touchscreens have support for a (Goodix) active pen, add
support for this. The info on how to detect when a pen is down and to
detect when the stylus buttons are pressed was lifted from the out
of tree Goodix driver with pen support written by Adya:
https://gitlab.com/AdyaAdya/goodix-touchscreen-linux-driver/
Since there is no way to tell if pen support is present, the registering
of the pen input_dev is delayed till the first pen event is detected.
This has been tested on a Trekstor Surftab duo W1, a Chuwi Hi13 and
a Cyberbook T116 tablet.

When converting a rumble into a periodic effect, for compatibility,
the magnitude is effectively calculated using:
magnitude = max(strong_rubble / 3 + weak_rubble / 6, 0x7fff);
The rumble magnitudes are both u16 and the resulting magnitude is
s16. The max is presumably an attempt to limit the result of the
calculation to the maximum possible magnitude for the s16 result,
and thus should be a min.
However in the case of strong = weak = 0xffff, the result of the first
part of the calculation is 0x7fff, meaning that the min would be
redundant anyway, so simply remove the current max.

Modern devices may redraw display at 60 Hz, make sure we have one input
sample per one frame. Reduce sample period to 15ms, so we would get up
to 66.6 samples per second, although realistically with all the jitter
and extra scheduling wiggle room, we would end up just above 60 samples
per second. This should be a good compromise between sampling too often
and sampling too seldom.

Currently the ili210x driver implements a threaded interrupt handler which
starts upon edge on the interrupt line, and then polls the touch controller
for samples. Every time a sample is obtained from the controller, the thread
function checks whether further polling is required, and if so, waits fixed
amount of time before polling for next sample.
The delay between consecutive samples can thus vary greatly, because the
I2C transfer required to retrieve the sample from the controller takes
different amount of time on different platforms. Furthermore, different
models of the touch controllers supported by this driver require different
delays during retrieval of samples too.
Instead of waiting fixed amount of time before polling for next sample,
determine how much time passed since the beginning of sampling cycle and
then wait only the remaining amount of time within the sampling cycle.
This makes the driver deliver samples with equal spacing between them.

The ili251x touch controller needs 5ms delay between sending I2C device
address and register address, and, writing or reading register data.
According to downstream ili251x example code, this 5ms delay is not
required when reading touch samples out of the controller. Implement
such a special case.

-F weight in perf script is broken.
# ./perf mem record
# ./perf script -F weight
Samples for 'dummy:HG' event do not have WEIGHT attribute set. Cannot
print 'weight' field.
The sample type, PERF_SAMPLE_WEIGHT_STRUCT, is an alternative of the
PERF_SAMPLE_WEIGHT sample type. They share the same space, weight. The
lower 32 bits are exactly the same for both sample type. The higher 32
bits may be different for different architecture. For a new kernel on
x86, the PERF_SAMPLE_WEIGHT_STRUCT is used. For an old kernel or other
ARCHs, the PERF_SAMPLE_WEIGHT is used.
With -F weight, current perf script will only check the input string
"weight" with the PERF_SAMPLE_WEIGHT sample type. Because the commit
ea8d0ed6eae3 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") didn't
update the PERF_SAMPLE_WEIGHT_STRUCT sample type for perf script. For a
new kernel on x86, the check fails.
Use PERF_SAMPLE_WEIGHT_TYPE, which supports both sample types, to
replace PERF_SAMPLE_WEIGHT

When perf.data is not written cleanly, we would like to process existing
data as much as possible (please see f_header.data.size == 0 condition
in perf_session__read_header). However, perf.data with partial data may
crash perf. Specifically, we see crash in 'perf script' for NULL
session->header.env.arch.
Fix this by checking session->header.env.arch before using it to determine
native_arch. Also split the if condition so it is easier to read.
Committer notes:
If it is a pipe, we already assume is a native arch, so no need to check
session->header.env.arch.

The Host Performance Buffer feature allows UFS read commands to carry the
physical media addresses along with the LBAs, thus allowing less internal
L2P-table switches in the device. HPB1.0 allowed a single LBA, while
HPB2.0 increases this capacity up to 255 blocks.
Carrying more than a single record, the read operation is no longer purely
of type "read" but a "hybrid" command: Writing the physical address to the
device in one operation and reading back the required payload in another.
The JEDEC HPB spec defines two commands for this operation:
HPB-WRITE-BUFFER (0x2) to write the physical addresses to device, and
HPB-READ to read the payload.
With the current HPB design the UFS driver has no alternative but to divide
the READ request into 2 separate commands: HPB-WRITE-BUFFER and HPB-READ.
This causes a great deal of aggravation to the block layer guys who
demanded that we completely revert the entire HPB driver regardless of the
huge amount of corporate effort already invested in it.
As a compromise, remove only the pieces that implement the 2.0
specification. This is done as a matter of urgency for the final 5.15
release.

Testing revealed a problem with how the reference tag was handled for
a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when
the controller is asked to generate the protection information
(i.e. not DIX). And as a result the initial reference tag would not be
set in the WRITE_INSERT case.
Separate handling of the REF_CHECK and REF_INCREMENT flags to align
with both the DIX spec and the MPI implementation.

Pull btrfs fixes from David Sterba:
"Last minute fixes for crash on 32bit architectures when compression is
in use. It's a regression introduced in 5.15-rc and I'd really like
not let this into the final release, fixes via stable trees would add
unnecessary delay.
The problem is on 32bit architectures with highmem enabled, the pages
for compression may need to be kmapped, while the patches removed that
as we don't use GFP_HIGHMEM allocations anymore. The pages that don't
come from local allocation still may be from highmem. Despite being on
32bit there's enough such ARM machines in use so it's not a marginal
issue.
I did full reverts of the patches one by one instead of a huge one.
There's one exception for the "lzo" revert as there was an
intermediate patch touching the same code to make it compatible with
subpage. I can't revert that one too, so the revert in lzo.c is
manual. Qu Wenruo has worked on that with me and verified the changes"

When calling this function, all the shadow memory is already populated
with kasan_early_shadow_pte which has PAGE_KERNEL protection.
kasan_populate_early_shadow write-protects the mapping of the range
of addresses passed in argument in zero_pte_populate, which actually
write-protects all the shadow memory mapping since kasan_early_shadow_pte
is used for all the shadow memory at this point. And then when using
memblock API to populate the shadow memory, the first write access to the
kernel stack triggers a trap. This becomes visible with the next commit
that contains a fix for asan-stack.
We already manually populate all the shadow memory in kasan_early_init
and we write-protect kasan_early_shadow_pte at the end of kasan_init
which makes the calls to kasan_populate_early_shadow superfluous so
we can remove them.
