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.
