Jonathan writes:

First set of new device support, features and cleanups for IIO in the 5.3 cycle

New device support
* mt6577
  - add supprot for the mt6765 which requires a few minor additional
    new features in the driver.

Yaml binding conversions
* adxl345
* isl29018
* tsl2583
* tsl2772

Minor features and improvements
* ad5758
  - declare an of_device_id table rather than just relying on the spi
    fallback which doesn't use the manufacturer id.
  - drop a set but not used variable left from previous refactor.
* ad7816
  - Add a bit more description to kconfig text.
* ad9523
  - change calculation order to improve frequency accuracy.
* adxl372
  - declare an of_device_id table
* adt7316
  - white space.
* at91_adc
  - Use dev_get_drvdata directly rather than boucing to the platform device
    and back again.
* cros_ec
  - add an id sysfs entry to bring in line with the other implementations.
* ds5522
  - drop a check on the of_node existing as we don't actually use it for
    anything.
* kxsd9
  - declare an of_device_id table.
* maxim_thermocouple
  - declare an of_device_id table.
* mt6577
  - add dt binding entry for mt8183 which is also supported.
* rcar-gyroadc
  - tidy up unnecessary error messages.
* stm32-dfsdm
  - improved error handling.
* stmpe-adc
  - drop an unnecessary variable assignment.
  - add an of_device_id table.
  - reinit completion on begin converstion to avoid a path in which
    previous round had been interrupted, also switch to non interruptible
    wait to avoid an issue with a user program using -pg
  - simplify interrupt handling by just having them always enabled.
  - reset all interrupts on startup and in the timeout handler to
    avoid getting stuck.
* sun4i-gpadc
  - SPDX
