Merge tag 'iio-for-5.4a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of new device support, features and cleanups for IIO in the 5.4 cycle

Note includes a merge from i3c tree to get support needed for stm_lsm6dsx driver
support for l3c devices.  Done from immutable branch.

A counter subsystem patche in here as well.

Alongside the new device support (which is always good), Chuhong's work
on using devres managed APIs has cleaned up a number of drivers.

New device support
* adis16460
  - New driver based on ADIS framework which needed addition of support
    for cs_change_delay. Includes device tree binding.
* cros_ec
  - Support fo the veyron-minnie which uses an older interface.
* lsm6dsx
  - Support for LSM6DSTR-C gyro + magnetometer sensor (new IDs mainly)
  - Support for ISM330DHCX acc + gyro sensor (extensive rework needed!)
* Maxim 5432
  - New driver support MAX5432-MAX5435 family of potentiometers.
* noa1305
  - New driver for this ON Semiconductor Ambient light sensor.

Features and cleanups
* tree wide
  - Drop error prints after platform_get_irq as already prints errors
    internally if any occur.
* docs
  - Document mounting matrix.
  - Fix a missing newline at end of file.
* ad2s1210
  - Switch to device managed APIs for all of probe and drop explicit remove.
* ad7192
  - Add of_device_id array to explicity handling DT bindings.
* ad7606
  - Lots of rework leading to support for software configure modes in ad7616
    parts.
  - Debugfs register access support.
* am2315
  - Switch to device managed APIs for all of probe and drop explicit remove.
* apds9960
  - Typo in module description.
* cm36651
  - Convert to i2c_new_dummy_device.
  - Swithc to device managed APIs for all of probe adn drop explicit remove.
* cros_ec
  - Calibscale support for accel, gyro and magnetometer.
  - Tidy up some error codes to return the error from the stack rather than
    -EIO.
  - Determine protocol version.
  - Add a sign vector to the core to fix sensor rotation if necessary.
    Cannot just be done with mount matrix as already in use in many devices.
  - Tidy up INFO_SCALE being in both the separate and shared lists.
  - Drop a lot of dplicate code from the cros-ec-accel-legacy driver
    and use the core provided code instead.
  - Make frequency range available to userspace.
* counter / ftm-quaddec
  - Switch to device managed APIs for all of probe adn drop explicit remove.
* hdc100x
  - Switch to device managed APIs for all of probe and drop explicit remove.
* hi8435
  - Use gpiod_set_value_cansleep as we don't care here and there is a
    board out there where it needs to sleep.
  - Switch to device managed APIs for all of probe and drop explict remove.
* hp03
  - Convert to i2c_new_dummy_device.
* maxim thermocouple
  - Switch to device managed APIs for all of probe and drop explicit remove.
* mmc35240
  - Fix typo in constant naming.
* mpu6050
  - Use devm_add_action_or_reset in place of explicit error handling.
  - Make text in Kconfig more explicit about which parts are supported.
* mxc4005
  - Switch to device managed APIs for all of probe and drop explicit remove.
* pms7003
  - Convert device tree bindings to yaml.
  - Add a MAINTAINERS entry
* sc27xx
  - Introduce a local struct device *dev pointer to avoid lots of deref.
  - Use devm_add_action_or_reset in place of explicit error handling.
* sca3000
  - Typo fix in naming.
* si1145
  - Switch to device managed APIs for all of probe and drop explicit remove.
* st_sensors
  - Lots of rework to enable switch to regmap.
  - Regmap conversion at the end.
  - Tidy up some inconsistencies in buffer setup ops.
  - Tidy up an oddity by dropping get_irq_data_ready function in favour
    of direct access.
  - Stop allocating buffer in buffer enable in favour of just embedding
    a large enough constant size buffer in the iio_priv accessed structure.
* st_lsm6dsx
  - l3c device support (LSM6DSO and LSM6DSR)
  - tidy up irq return logic which was strangely written.
  - fix up an ABI quirk where this driver used separate scale
    attributes, even though they were always shared by type.
* stk33xx
  - Device tree bindings include manufacturer ID.
* stm32-adc
  - Add control for supply to analog switches including DT bindings.
* stm32 timer
  - Drop the quadrature mode support.  Believed there were no users so
    take this opportunity to drop this unwanted ABI.
* tsl2772
  - Switch to device mangage APIs for all of probe and drop explicit remove.
  - Use regulator_bulk_* APIs to reduce repitition.
* veml6070
  - Convert to i2c_new_dummy_device.

 "A filesystem-dax and device-dax fix for v5.3.

  The filesystem-dax fix is tagged for stable as the implementation has

  truncate to dax pages.

  The device-dax change fixes up a regression this cycle from the
