Pull char/misc/IIO/etc driver updates from Greg KH:
 "Here is the big set of char, misc, iio, counter, fpga, and other small
  driver subsystems for 7.3-rc1.

  Overall, due to some driver removals we only added a bit more code
  than removed, which was a nice change. Highlights in this merge
  request are:

   - Loads of IIO driver updates and additions

   - binder driver updates (more on that below...)

   - Removal of the SGI XP and GRU drivers as they are not used anymore
     and turn out to be pretty insecure overall

   - Removal of the obsolete ibmasm driver as it's not being used
     anymore

   - Coresight driver updates and additions

   - Mei driver udpates

   - Counter driver updates

   - FPGA driver updates

   - ICC driver updates

   - lots and lots of other tiny driver updates to resolve reported
     issues

  All of these have been in linux-next for a while"

IIO new device support, features, cleanup for 7.3

Includes a merge of 7.2-rc2 to pick up the changes around
mod_devicetable.h and reduce resulting conflicts around includes.

New device support

  over SPI
- Add support for AD5316R, AD5674, AD5697R and AD5696 DACs over I2C
- Significant driver refactoring prior to these additions, partly to reduce
  bus traffic and to add triggered buffer and gain control support. An
  earlier set added support for missing supplies, reset and LDAC GPIO.

  26.5 GHz.
- Included infrastructure to handle higher precision attributes with
  extensive tests
adi,ltc2378-20

  LTC2376, LTC2377, LTC2378, LTC2379 and LTC23980 ADCs with both high speed
  capture via appropriate backend and conventional triggered buffer SPI
  capture.
invensense,icm42607
- New driver for this IMU.
mediateck,mt6323
- New driver for this PMIC ADC.
microchip,mcp47a1

  channel type.
st,vl53l1x
- Refactors to improve readability.
ti,ads112c14

  some new ABI for input chopping, particular useful for resistive sensors
  like thermocouples or Wheatstone bridges.

- Support buffered reads.
ti,tmp117
- (trivial) Add support for the tmp119 temperature sensor.
xilinx,versal-sysmon
- New ADC driver for this block found on various FPGAs including various
  bus interfaces, threshold and oversampling support.

dt binding updates
------------------
new shared bindings
- excitation-channels and excitation-current-nanoamp allow per channel
  specification of currents used for resistive sensor measurement.
- reference-sources property to allow selection of a per channel reference.
rockchip,saradc
- Add RV1106 which is compatible with the RV3588.

Features
--------

buffer-dmaengine
- Allow cyclic buffers, useful for repeating sequence generation with DACs.

  returned an error.
hid,sensors-als

Cleanups, minor fixes
---------------------

Minor cleanups not mentioned at all in this summary such
as white space fixes or typos.

Affecting various drivers
- Cleanup of conditionals that had no affect.
- Drop some runtime pm local wrappers as now runtime_pm does the
  mark_last_busy part inside the put, these provide no useful code
  deduplication or readability advantages over directly calling the
  runtime_pm functions.
- Return 0 from write_raw() on success.
- Use of dev_err_probe() to simplify code and sometimes provide useful
  info for deferred probe debugging.
- Drop some redundant error prints where the called function already
  provides information on errors.
- Make some read only arrays in functions static.
- Fix up missing handling of regcache_sync() errors.
- Drop some false kernel-doc markings.
- Add missing MODULE_DEVICE_TABLE for some of_match_id tables.
- Use local variables for things like the struct device to shorten and
  improve readability of code.
- Drop some unused structure elements.
- Reorder dds.h macro parameters to be inline with others.
- Header reorders and IWYU. Often part of a more significant series.
- Remove abstractions designed to allow a driver to support multiple device
  types, when they have been around a long time and only the original part
  showed up.
- Initialize spi_device_id arrays using member names following dropping of
  driver data from drivers that didn't actually use it.
- Catch up with i2c_device_id tables added since previous effort to use
  named initializers for all those.
- Use kernel types in a few places instead of standard C ones or bare
  unsigned.

Misc
- Update Xilinx AMS maintainer.
- Update email address for Maxwell Doose.
- Update email address for Siratul Islam.
- Update email address for Tomasz Duszynski and re-add Tomasz to
  various maintainer entries.
Docs

  flexibility in input to differential pair mapping. Intended to
  provide a strong signal to userspace that a channel is differential.
adi,ad_sigma_delta
- Allow COMPILE_TEST without any users.
adi,ad2s1201
- Refactor trigger handler to avoid mix of guard() and goto.
adi,ad5686
- Avoid potential NULL dereference is user forces a driver bind.
adi,ad5696
- Add a couple of missing entries to the of_match_id table and update
  binding to match.
atmel,ad91_adc

  (to come)

  the setup is done to avoid potentially dropping data.

- Drop an unreachable return.
invensens,icm45600
- Harden against bad value of FIFO sample count from device.
- Use i2c_match_data if firmware table sourced match data isn't available.
nxp,mpl1115
- Ensure runtime_pm is balanced on error in probe.
rohm,bm1390
- Make the driver slightly more likely to recover from transient errors.
sensiron,sgp30
- Handle thread creation errors.
st,lsm6dsx
- Update the enable mask when doing sensor fusion to avoid incorrect fifo
  data handling.
st,stm32-dfsdm
- Treat dt flags as booleans.
ti,ads1015
- Switch to devm helpers which simplified code and closed a resource leak.
ti,opt3001
- Split complicated opt3001_get_processed() logic into irq an no irq
  helper functions.
- Use devm to simplify code.

Linux 7.2

Prepare input updates for 7.3 merge window.

Pull input updates from Dmitry Torokhov:

 - Fixes for information leaks and OOB accesses across several drivers,
   including evdev, focaltech, edt-ft5x06, iforce, and cs40l50-vibra

 - Improvements to the synaptics-rmi4 driver to properly handle F54
   worker errors and prevent buffer overflows

 - Input validation fixes in the hynitron_cstxxx touchscreen driver to
   prevent issues with invalid finger IDs and touch counts

 - Fixes for use-after-free and initialization bugs in the byd mouse and
   psxpad-spi drivers

 - New quirks for the atkbd driver to make keyboard work on HONOR and
   Xiaomi laptops

 - Support for the ZENAIM LEVERLESS controller in the xpad driver.

  Input: edt-ft5x06 - ignore contacts with an out-of-range slot id
  Input: byd - synchronize timer deletion before freeing private data

Instead of hardcoding PA-RISC specific keycode tables into atkbd via
compile-time inclusion, have the gscps2 PS/2 port driver attach a
linux,keymap software node device property to the serio device when
a keyboard port is registered. This allows atkbd to dynamically fetch
and apply the custom keymap when probing the port using generic
firmware property helpers, removing architecture-specific hacks from
generic keyboard driver code.

Co-locate the keymap definitions with the serio port driver by moving
hpps2atkbd.h from drivers/input/keyboard/ to drivers/input/serio/.
To handle the five conflicting keys on RDI PrecisionBook laptops without
runtime model string checks or duplicate keymap tables in memory, add
CONFIG_SERIO_GSCPS2_RDI_KEYCODES to drivers/input/serio/Kconfig and
resolve the conflicting keycodes at compile time via preprocessor
macros.

Simplify the driver by using the block-scope guard(pm_runtime_active)
instead of manually invoking pm_runtime_get_sync() and
pm_runtime_put().

Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

The driver requests the interrupt during probe, which by default enables
it. If the bootloader left the keypad interrupts enabled, or if a
spurious interrupt fires early before the driver is fully initialized
and clocks are enabled, the interrupt handler will attempt to read
registers and may cause a synchronous external abort.

Fix this by requesting the interrupt with IRQF_NO_AUTOEN, keeping it
disabled during probe. Enable the interrupt in samsung_keypad_start()
when the device is opened and ready, and disable it in
samsung_keypad_stop() when the device is closed. Remove the redundant
re-enabling of the interrupt at the end of samsung_keypad_stop().

Additionally, manually clear the pending interrupt status during system
resume when the device is closed to avoid immediate resume.
