Greg Kroah-Hartman 6771fb0b94 1st set of new IIO/counter device support, features and cleanup for 5.14
There are a couple of large cleanup sets in here alongside a number of new
 drivers.
 
 Note an immutable branch merged to add a stub for i2c_verify_client()
 as needed to avoid a build issue in the fxls8962af driver as a result of a
 workaround for a device errata that only applies when i2c interface is used.
 
 Counters
 ========
 
 New device support
 * intel,quadrature encoder peripheral found on Elkhart Lake platforms.
   - New driver.
 
 IIO

 New device support
 * amstaos,tsl2591 ambient light sensor.
   - New driver + bindings
   - Follow up fix to ensure some local variables are suitable for error
     handling.
 * fsl,fxls8962af + fsl,fxls8964af accelerometers
   - New driver + bindings

     by adding a stub to i2c.
 * kionix,kxcjk-1013
   - Add support for KX023-1025 device.  Mostly a different register map
     that needed to be supported.

   - Rework of st,sensors driver to cleanly support this new glue driver
     that enables the two parts of the LSM9DS0.

     drivers such as resistive-adc-touch.

     check.

   - New driver + bindings

   - Add missing dt-binding doc
 * adi,ad7476
   - Add missing dt-binding doc

   - Add missing dt-binding doc
 * iio-rescale
   - Support handling of processed channels from provider.  Some ADCs
     require (typically non linear) calibration functions to be applied,
     and so provide only IIO_CHAN_INFO_PROCESSED read back. They can be
     used as providers to the iio-rescale driver which needs to handle them
     somewhat differently from IIO_CHAN_INFO_RAW

     refactoring of existing driver.

 Cleanup / minor fixes
 * core
   - Use devm_add_action_or_reset() to replace boilerplate in several
     driver and core IIO devm_* functions.
   - Fix an error path issue introduced by above, that could return an
     error pointer rather than the expected null from dev_iio_device_alloc()
   - Move more IIO internals related fields from struct iio_dev to
     struct iio_dev_opaque.
   - Drop unused final update of in_loc in demux setup.
 * Docs
   - Move some docs from driver specific to core dos to avoid replication
     of names which the documentation builder does not allow.
     Note this means adding a few device specific notes to the general docs
     to cover the more unusual uses of the ABI.
   - ABI: Move old buffer/* and scan_elements/* docs to obsolete as now we
     have the bufferX/* variant.  Not we are not getting rid of these
     interfaces, just encouraging new code to use the new interface.
 * IIO wide:
   - Tidy up new cases of dev.parent etc being set in drivers as the core
     now does it.
   - Fix more cases of possible miss-aligned buffers when passed to
     iio_push_to_buffers_with_timestamp().  Note we only have one known
     instance of anyone seeing this bug actually happening, so this has been
     a low priority cleanup effort for several cycles.
   - sysfs_emit() used in more drivers.
   - Runtime pm tidy up and use of pm_runtime_resume_and_get()
   - Buffer alignment fixes as iio_push_to_buffers_with_timestamp requires
     that the timestamp when inserted by naturally aligned + consumers can
     assume that all fields are naturally aligned. Part of a long running
     effort, with at least 2 more series to come tackling additional
     variants.
   - Stop specifying "mount-matrix" property name in every lookup of the
     mount matrix from firmware by hard coding it in the core.
 * adi,ad7476
   - Handle the variety of different regulators used by the parts supported
     by this driver (came up in dt-binding review)
 * adi,ad7746
   - Trivial drop of if (ret) return ret; return 0; pattern
   - Tidy up comments
   - Pull capdac setup out to own function.
 * adi,ad7766
   - Trivial drop of if (ret) return ret; return 0; pattern
 * adi,adis
   - Avoid returning error codes in interrupt handlers.
   - Handle a failure in spi_write in the trigger handler.
   - Rework to add updating of device page after changing it.
   - Don't push data to IIO buffers when read failed.
   - Add configuration of burst max speed to core avoid handling this in
     each driver.
   - Use the adis_dev_lock() helper in adis16260 and adis16136 drivers.
   - Excessive includes cleanup via include-what-you-use static checker
     after zero day highlighted that these needed updating.
 * afe
   - Amend binding to add #io-channel-cells, thus allowing this IIO
     consumer to also be an IIO provider.
 * aosong,am2315
   - Drop ACPI id. Unlikely this one is in the wild and it isn't valid
     ACPI naming.
 * bosch,bma180
   - Adding missing bandwidth settings (500, 1000 Hz)
 * bosch,bme680
   - Drop ACPI id. Unlikely this one is in the wild and it isn't valid
