56d784d177 1st set of IIO new device support, feature and cleanup for 6.2 (take2)
We have finally managed to take the mlock mutex entirely private so as
 to avoid it being used for multiple purposes.  Now it is just used to
 protect device mode transitions (typically to and from buffered capture).
 
 Includes merge of an immutable i2c branch to get the new
 i2c_client_get_device_id() (thanks to Wolfram for providing the branch).
 
 Based on rc3 to pick up some precursor fixes from early in the cycle and
 avoid an unnecessarily messy history.
 
 New device support
 * adi,ad4310
   - New driver to support this very flexible measurement device including
     a 24 bit ADC. Later fix for documentation build issue.
 * adi,adxl355
   - Add support of the ADXL359 accelerometer.
 * adi,ltc2983
   - Support additional variants of the temperatures sensor:
     LTC2984 with an EEPROM
     LTC2985, LTC2986 with only 10 channels.
 * invensense,icm42600
   - Add support for icm42631 (needed only ID and WHOAMI)
 * kionix,kx022a
   - New driver for this 3 axis accelerometer.
 * maxim,max11401
   - New driver to support this 24-bit 10 channel ADC.
     Includes some new ABI to support configuration of notch filters.
 * mediatek,mt6370
   - Add new driver to support the ADC part of the mt6370.
 * st,lsm6dsx
   - Add support for LSM6DSV accelerometer and gyroscope. Simple additional
     of chip specific data and IDs.
   - Add support for LSM6DSV16X accelerometer and gyroscope.  Compatible with
     features currently implemented for the LSM6DSV.
 * st,stm32-adc
   - Add support for stm32pm13x SoCs.
 
 core / subsystem wide:
  - Add new IIO_STATIC_CONST_DEVICE_ATTR() which is a dance necessary to
    allow for the wrapping of attributes in the code that duplicates them
    for multiple buffers.
  - Harden against future issues with expectation that all buffer attributes
    are iio_dev_attrs by changing the code to take an array of pointers
    of the correct type.
  - Last transitions of drivers to local locks rather than missuses of mlock.
  - Add an iio_device_claim_buffer_mode() callback to avoid a race in the
    max30100 driver without directly using mlock.
  - Move mlock to the opaque IIO device structure to prevent misuse.
  - Add missing spi_device_id tables to support auto loading of modules.
  - Update some ADI maintainers in DT bindings.
  - A few more moves of bus drivers and core module sets to export
    name spaces.
  - Extensive use of new devm_regulator_get_enable() and friends.
  - Switch a bunch of i2c drivers to probe_new() including the bmp280
    which makes use of the new i2c_client_get_device_id() helper to
    simplify this change.
 
 dt-bindings:
  - More use of spi-peripheral-props.yaml.
 
 Features
 * freescale,mpl115
   - Use runtime PM to implement shutdown GPIO support.
 * melexis,mlx90632
   - More sophisticated runtime power management
   - Provide access to sampling frequency.
   - Trivial follow up fixes.
 * microchip,mcp3911
   - Support control of PGA.
 * st,lsm6dsx
   - Add support for software triggers for cases where the IRQ lines
     are not wired up.
 * vishay,vcnl4000
   - Add control of integration time.
 
 Minor cleanups and fixes
 * adi,ad4130
   - Improve ABI documentation formatting.
   - Kconfig dependency fixup.
 * adi,ad5758
   - Minor dt binding fix.
 * adi,ad9834
   - Tidy up line breaks.
 * adi,ade7854
   - Minor improvement in code clarity by replacing a ternary.
 * adi,admv8818
   - Harden code against hardware returning wrong values.
 * adi,adxl355
   - Warn only if unknown device ID detected to allow for fall back
     device tree compatibles on future devices.
 * adi,ltc2983
   - dt-bindings clarifications and general improvements.
   - Ensure DMA safe buffer for bulk writes without relying on current
     regmap implementation choices.

   - Fix up a disconnect between event enable attributes and what was
     enabled.

MPL115 supports shutdown gpio which can be used to set the state

This patch enables runtime PM on MPL115 to increase power savings.

According to spec., a wakeup time period of ~5 ms exists between
waking up and actually communicating with the device. This is
implemented using sleep delay.

only try the reset after timeout once if errors persist.

ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Avoid unnecessary pollution of the global symbol namespace by
moving library functions in to a specific namespace and import
that into the drivers that make use of the functions.

Do not trust the fact that iio.h includes of.h which in turn includes
all the headers we are relying on.

The ultimate goal is to actually drop of.h from iio.h.

When sensor location is known, populate iio sysfs "label" attribute:

* "accel-base" : the sensor is in the base of the convertible (2-1)
  device.
* "accel-display" : the sensor is in the lid/display plane of the
  device.
* "accel-camera" : the sensor is in the swivel camera subassembly.

The non-standard |location| attribute is removed, the field |loc| in
cros_ec_sensors_core_state is removed.

It apply to standalone accelerometer as well as IMU (accelerometer +
gyroscope) and sensors where the location is known (light).

An odr_lock has been introduced to protect local accesses to the odr

drop these extra mutex_lock/unlock() calls.

02e2af20f4 Char/Misc and other driver updates for 5.18-rc1
Here is the big set of char/misc and other small driver subsystem
 updates for 5.18-rc1.
 
 Included in here are merges from driver subsystems which contain:
 	- iio driver updates and new drivers
 	- fsi driver updates
 	- fpga driver updates
 	- habanalabs driver updates and support for new hardware
 	- soundwire driver updates and new drivers
 	- phy driver updates and new drivers
 	- coresight driver updates
 	- icc driver updates
 
 Individual changes include:
 	- mei driver updates
 	- interconnect driver updates
 	- new PECI driver subsystem added
 	- vmci driver updates
 	- lots of tiny misc/char driver updates
 
 There will be two merge conflicts with your tree, one in MAINTAINERS
 which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
 which also should be easy to resolve.
 
 All of these have been in linux-next for a while with no reported
 problems.

902b291fc6 iio:pressure:mpl3115: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() etc
Letting the compiler remove these functions when the kernel is built
without CONFIG_PM_SLEEP support is simpler and less error prone than the
use of #ifdef based config guards.

Removing instances of this approach from IIO also stops them being
copied into new drivers.

d4786e7df0 iio:st-sensors: Remove duplicate MODULE_*
The core module and type specific core modules are made up of
several files. There is no benefit in duplicating the MODULE_* macros
in each file so remove them.

Noticed whilst adding MODULE_IMPORT_NS() as I missed some files and
it still worked, making it clear not all of these blocks were needed.

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.
