1st round of IIO new device support, features and cleanups in the 4.20 cycle.

There is a merge commit in here to pull in regmap support for repeatedly
reading the same register (to read out FIFOs).  Used by the adxl372 driver.
This will find uses elsewhere once we tidy up various drivers that are
effectively doing this and relying on not enabling regcache.

New device support
* Analog devices ADXL372 accelerometer
  - new driver for this accelerometer including fifo and and interrupt support.
    Follow up patches enforce trigger validation, add sampling frequency
    control and filter bandwidth control.  A later series added i2c support
    to the existing SPI support.
* ST lsm6dsx
  - rework and add support fo the LSM6DSO 6 axis mems sensor.
* Linear LTC 1660 DAC
  - new driver supporting the LTC 1660 and LTC 1665 SPI DACs.
* Microchip mcp3911 ADC.
  - new driver for this integrated analog front end and ADC.
* Qualcomm SPMI PMIC5 adc driver
  - using the spmi framework, new driver and bindings for this ADC.
    Follow up patch adds some missing channels.

Features
* ad5758
  - support hard reset using a gpio (if provided).
* mpu6050
  - Regulator support
* qcom-spmi-adc5
  - Sanity check the channel numbers provided by DT to make sure the
    driver actually knows about them.
* sc27xx
  - give raw data for channel 20 as it's used on all known boards for
    the headset which needs a custom converstion function.  If it turns
    out someone builds a board where this isn't true we will deal with it
    when it happens.
  - add ADC scale calibration.
* tsl2772
  - support device tree binding to set the proximity led settings.
  - regulator supprot.
  - binding for apds9930 - trivial addition as register compatible with tsl2772.

Cleanups / Minor fixes

* adxl345
  - supress a static checker warning but explicitly checking if the id
    object is null.
* bh1750
  - avoid CONFIG_PM_SLEEP checks.
  - SPDX.
* bme680
  - spelling mistake
  - use clamp rather than open coding.
  - white space and other similar fixes.
  - rename MSK to MASK for clarifty and use GENMASK to specify them.
  - use the FIELD_GET macro rather than a very odd accessor of dividing by
    16 to get the shift.
  - rework to share handing for oversampling of the various channels in a
    unified way.
  - check explicitly for val2 in write_raw function to ensure it is 0.
  - drop some field defines that don't add anything.
* dpot-adc
  - SPDX
* envelope detector
  - SPDX
* isl29501
  - fix an ancient compiler warning mostly because it results in much
    nicer code.
* max30102
  - mark switch fall throughs.
* max44000
  - drop an unused variable.
* max512
  - avoid CONFIG_PM_SLEEP checks.
* max5481
  - use of_device_get_match_data rather than open coding it.
* max5821
  - avoid CONFIG_PM_SLEEP checks.
* max9611
  - explicity cast an enum to an integer to make it totally clear that
    this is intended.
* mcp4018
  - fix an inconsistent MODULE_LICENSE.
  - use of_device_get_match_data rather than open coding it.
* mcp4531
  - use of_device_get_match_data rather than open coding it.
  - SPDX
* mcp4725
  - avoid CONFIG_PM_SLEEP checks.
* mcp4922
  - Fix error handling and prevent writing a negative to when setting the
    output voltage.
* ms5611
  - drop deprecated compatible strings without manufacturer from being
    explicitly listed.  They are handled anyway.
  - SPDX
* multiplexer
  - SPDX
* qcom-vadc
  - fix inconsistent documentation for reg.
* ti-dac5571
  - provide and of_match_table.

* treewide
  - update Michael Hennerich's email address.
  - Use %pOFn rather than device_node.name.
* documentation.
  - tidy up a wrong kernel version for the introduction of the
    position_relative ABI.
