First set of IIO new device support, features and cleanup for 5.19

Usual mixed bag. Stand out this time is Andy Shevchenko's continuing
effort to move drivers over the generic firmware interfaces.

Device support
* sprd,sc2720
  - upm9620 binding addition.
  - Refactor and support for sc2720, sc2721 and sc2730.
* ti,ads1015
  - Refactor driver and add support for TLA2024.

Device support (IDs only)
* invensense,mpu6050
  - Add ID for ICM-20608-D.
* st,accel:
  -  Add ID for lis302dl.
* st,lsm6dsx
  - Add support for ASM330LHHX (can fallback to LSM6DSR.)

Features
* convert drivers to device properties
  - IIO core
  - adi,ad7266
  - adi,adis16480
  - adi,adxl355
  - bosch,bmi160
  - domintech,dmard06
  - fsl,fxas21002c
  - invensense,mpu3050
  - linear,ltc2983
  - linear,ltc2632
  - maxbotix,mb1232
  - maxim,max31856
  - maxim,max31865
  - multiplexer
  - ping
  - rescale
  - taos,tsl2772
* core
  - Add runtime check on whether realbits fit in storagebits for each
    channel.
* adi,ad_sigma_delta
  - Add sequencer support and relevant update_scan_mode callbacks for
    adi,ad7192 and adi,ad7124.

Cleanup and minor fixes
* MAINTAINERS
  - Update Lorenzo Bianconi's email address for IIO drivers.
  - Add entry for ad3552r and update maintainer in dt-binding doc.
* tree-wide
  - Replace strtobool() with kstrtobool().
  - Drop false OF dependencies.
* core
  - Tidy up and document IIO modes.
  - Take iio_buffer_enabled() out of header allowing current_mode to be
    moved to the opaque structure.
  - As all kfifo buffers use the same mode value, drop that parameter
    and set it unconditionally.
  - White space fixes and similar.
  - Drop use of list iterator variable for
    list_for_each_entry_continue_reverse and use list_prepare_entry to
    restart.
* sysfs-trigger
  - Replace use of 'found' variable with dedicate list iterator variable.
* adi,ad7124
  - Drop misleading shift.
* adi,ad2s1210
  - Remove redundant local variable assignment.
* adi,adis16480
  - Use local device pointer to reduce repetition.
  - Improve handling of clocks.
* domintech,dmard09
  - White space.
* dummy driver
  - Improve error handling.
* fsl,mma8452
  - Add missing documentation of name element.
* invensense,mpu3050
  - Stop remove() returning non 0.
* kionix,kxsd9
  - White space.
* linear,ltc2688
  - Use local variable for struct device.
  - Combine of_node_put() error handling paths.
* linear,ltc2983
  - Avoid use of constants in messages where a define is available.
* microchip,mcp4131
  - Fix compatible in dt example.
* pni,rm3100
  - Stop directly accessing iio_dev->current_mode just to find out
    if the buffer is enabled.
* renesas,rzg2l
  - Relax kconfig constraint to include newer devices.
* sprd,sc27xx
  - Fix wrong scaling mask.
  - Improve the calibration values.
* samsung,ssp
  - Replace a 'found' variable in favor of an explicit value that was
    found.
* sensortek,stk3xx
  - Add proximity-near-level binding and driver support.
* st,st_sensors:
  - Drop unused accel_type enum.
  - Return early in *_write_raw()
  - Drop unnecessary locking in _avail functions.
  - Add local lock to protect odr against concurrent updates allowing
    mlock to no longer be used outside of the core.
  - Use iio_device_claim_direct_mode() rather than racy checking of
    the current mode.
* st,stmpe-adc
  - Fix checks on wait_for_completion_timeout().
  - Allow use of of_device_id for matching.
* st,stm32-dfsdm
  - Stop accessing iio_dev->current_mode to find out if the buffer
    is enabled (so we can hide that variable in the opaque structure)
* st,vl53l0x
  - Fix checks on wait_for_completion_timeout.
* ti,ads1015
  - Add missing ID for ti,ads1115 in binding doc.
  - Convert from repeated chip ID look up to selecting static const
    data.
  - Switch to read_avail() callback.
* ti,ads8688
  - Use of_device_id for driver matching.
* ti,palmas-adc
  - Drop a warning on minor calibration mismatch leading to slightly
    negative values after applying the calibration.
