I have a ST1633 touch controller which fails to probe due to a timeout
waiting for the controller to become ready. Increasing the minimum
delay to 100ms ensures that the probe sequence completes successfully.
The ST1633 datasheet says nothing about the maximum delay here and the
ST1232 I2C protocol document says "wait until" with no notion of a
timeout.
Since this only runs once during probe, being generous with the timout
seems reasonable and most likely the device will become ready
eventually.
(It may be worth noting that I saw this issue with a PREEMPT_RT patched
kernel which probably has tighter wakeups from usleep_range() than other
preemption models.)
Fixes: f605be6a57b4 ("Input: st1232 - wait until device is ready before reading resolution")

Currently autoloading for SPI devices does not use the DT ID table, it uses
SPI modalises. Supporting OF modalises is going to be difficult if not
impractical, an attempt was made but has been reverted, so ensure that
module autoloading works for this driver by adding a SPI device ID table.

The helper function devm_add_action_or_reset() will internally
call devm_add_action(), and if devm_add_action() fails then it will
execute the action mentioned and return the error code. So
use devm_add_action_or_reset() instead of devm_add_action()
to simplify the error handling, reduce the code.

Some Goodix touchscreen controllers, such as for example the GT912,
don't have flash-storage for their firmware.
These models require the OS to load the firmware at runtime, as well as
some other special handling. Add support for this to the goodix driver.
This patch was developed and tested on a Glavey TM800A550L tablet.
Note the "goodix,main-clk" and "firmware-name" device-properties used
by the new code are *not* documented in the
Documentation/devicetree/bindings/input/touchscreen/goodix.yaml
device-tree bindings for now.
Not documenting these is intentional. This is done because this code has
only been tested on x86/ACPI so far, where devicetree is not used.
Instead these properties are set through a software-fwnode attached to the
device by the drivers/platform/x86/touchscreen_dmi.c code. This means that
the use of this properties for now is purely a kernel-internal thing and
the name/working of the properties may still be changed for now.

Make the goodix_i2c_read() and goodix_i2c_write*() helpers log errors
themselves. This allows removing all the error logging from their callers.
This already results in a nice cleanup with the current code and it also
helps to make the upcoming support for controllers without flash cleaner.

Refactor reset handling a bit, change the main reset handler
into a new goodix_reset_no_int_sync() helper and add a
goodix_reset() wrapper which calls goodix_int_sync()
separately.
Also push the dev_err() call on reset failure into the
goodix_reset_no_int_sync() and goodix_int_sync() functions,
so that we don't need to have separate dev_err() calls in
all their callers.
This is a preparation patch for adding support for controllers
without flash, which need to have their firmware uploaded and
need some other special handling too.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.
So, use the struct_size() helper to do the arithmetic instead of the
argument "size + count * size" in the kzalloc() function.

This adds support for Cypress StreetFighter touchkey controllers such
as sf3155. This driver supports managing regulators and generating
input events.
Due to lack of documentation, this driver is entirely based on
information gathered from a driver written for an old Android kernel
fork[1][2].

A new warning in clang points out a few places in this driver where a
bitwise OR is being used with boolean types:
drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical]
data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This use of a bitwise OR is intentional, as bitwise operations do not
short circuit, which allows all the calls to touchscreen_get_prop_u32()
to happen so that the last parameter is initialized while coalescing the
results of the calls to make a decision after they are all evaluated.
To make this clearer to the compiler, use the '|=' operator to assign
the result of each touchscreen_get_prop_u32() call to data_present,
which keeps the meaning of the code the same but makes it obvious that
every one of these calls is expected to happen.

On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an
associated clock. Accessing the registers requires that this clock is
enabled. Binding the driver on at least i.MX7S and i.MX8MP while not
having the clock enabled results in a complete hang of the machine.
(This usually only happens if snvs_pwrkey is built as a module and the
rtc-snvs driver isn't already bound because at bootup the required clk
is on and only gets disabled when the clk framework disables unused clks
late during boot.)
This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add
snvs clock to pwrkey").

Similar to controllers found Voxel, Delbin, Magpie and Bobba, the one found
in Whitebox does not need to be reset after issuing power-on command, and
skipping reset saves resume time.

This reverts commit 81c7c0a350bfe9306ad9fb10356534ede8f4ab31. The idea
to make write method mandatory was flawed as several client drivers
(such as atkbd) check for presence of write() method to adjust behavior
of the driver.

Creating a software node and supplying that for the device
instead of only the device properties in it. A software
node was always created in any case to hold the additional
device properties, so this change does not have any real
effect.
This change makes it possible to remove support for the
problematic "dangling" device properties from i2c subsystem,
i.e. the "properties" member from struct i2c_board_info. The
problems caused by them are not related to this driver.

The Actions Semi ATC260x PMICs are able to manage an onkey button.
This driver exposes the ATC260x onkey as an input device. It can also
be configured to force a system reset on a long key-press with an
adjustable duration.
The currently supported chip variants are ATC2603C and ATC2609A.

Pull ARM SoC driver updates from Arnd Bergmann:
"Updates for SoC specific drivers include a few subsystems that have
their own maintainers but send them through the soc tree:
TEE/OP-TEE:
- Add tracepoints around calls to secure world
Memory controller drivers:
- Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
- Add debug statistics to Tegra20 memory controller
- Update Tegra bindings and convert to dtschema
ARM SCMI Firmware:
- Support for modular SCMI protocols and vendor specific extensions
- New SCMI IIO driver
- Per-cpu DVFS
The other driver changes are all from the platform maintainers
directly and reflect the drivers that don't fit into any other
subsystem as well as treewide changes for a particular platform.
SoCFPGA:
- Various cleanups contributed by Krzysztof Kozlowski
Mediatek:
- add MT8183 support to mutex driver
- MMSYS: use per SoC array to describe the possible routing
- add MMSYS support for MT8183 and MT8167
- add support for PMIC wrapper with integrated arbiter
- add support for MT8192/MT6873
Tegra:
- Bug fixes to PMC and clock drivers
NXP/i.MX:
- Update SCU power domain driver to keep console domain power on.
- Add missing ADC1 power domain to SCU power domain driver.
- Update comments for single global power domain in SCU power domain
driver.
- Add i.MX51/i.MX53 unique id support to i.MX SoC driver.
NXP/FSL SoC driver updates for v5.13
- Add ACPI support for RCPM driver
- Use generic io{read,write} for QE drivers after performance
optimized for PowerPC
- Fix QBMAN probe to cleanup HW states correctly for kexec
- Various cleanup and style fix for QBMAN/QE/GUTS drivers
OMAP:
- Preparation to use devicetree for genpd
- ti-sysc needs iorange check improved when the interconnect target
module has no control registers listed
- ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to
avoid issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as
we now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and
dra7
- omap-prm driver needs to enable autoidle retention support for
omap4
- omap5 clocks are missing gpmc and ocmc clock registers
- pci-dra7xx now needs to use builtin_platform_driver instead of
using builtin_platform_driver_probe for deferred probe to work
Raspberry Pi:
- Fix-up all RPi firmware drivers so as for unbind to happen in an
orderly fashion
- Support for RPi's PoE hat PWM bus
Qualcomm
- Improved detection for SCM calling conventions
- Support for OEM specific wifi firmware path
- Added drivers for SC7280/SM8350: RPMH, LLCC< AOSS QMP"
