Jonathan writes:

1st set of IIO new device support, features and cleanup for 6.1

This includes Nuno Sa's work to move the IIO core over to generic firmware
properties rather than having DT specific code paths. Combined with Andy
Shevchenko's long term work on drivers, this leaves IIO in a good state for
handling other firmware types.

New device support
- liteon,ltrf216a
  * New driver and dt bindings to support this Light sensor.
- maxim,max11205
  * New driver for this 16bit single channel ADC.
- memsensing,msa311
  * New driver for this accelerometer. Includes a string helper for read/write.
- richtek,rtq6056
  * New driver and dt binding to support this current monitor used to measure
    power usage.
- yamaha,yas530
  * Support the YAS537 variant (series includes several fixes for other parts
    and new driver features).

Staging graduation
- adi,ad7746 CDC. Cleanup conducted against set of roadtest tests using
  the posted RFC of that framework.

Features
- core
  * Large rework to make all the core IIO code use generic firmware properties.
    Includes switching some drivers over as well using newly provided
    generic interfaces and allowing removal of DT specific ones.
  * Support for gesture event types for single and double tap. Used in
    bosch,bma400.
- atmel,at91-sama5d2
  * Add support for temperature sensor which uses two muxed inputs to estimate
    the temperature.
  * Handle trackx bits of EMR register to improve temp sampling accuracy.
  * Runtime PM support.
- liteon,ltrf216a
  * Add a _raw channel output to allow working around an issue with
    differing conversions equations that breaks some user space controls.
- mexelis,mlx90632
  * Support regulator control.
- ti,tsc2046
  * External reference voltage support.

Clean up and minor fixes
- Tree-wide
  * devm_clk_get_enabled() replacements of opencoded equivalent.
  * Remaining IIO_DMA_MINALIGN conversions (the staging/iio drivers).
  * Various minor warning and similar cleanup such as missing static
    markings.
  * strlcpy() to strscpy() for cases where return value not checked.
  * provide units.h entries for more HZ units and use them in drivers.
- dt-bindings cleanup
  * Drop maintainers listss where the email address is bouncing.
  * Switch spi devices over to using spi-peripheral.yaml
  * Add some missing unevaluatedProperties / additionalProperties: false
    entries.
- ABI docs
  * Add some missing channel type specific sampling frequency entries.
  * Add parameter names for callback parameters.
- MAINTAINERS
  * Fix wrong ADI forum links.
- core
  * lockdep class per device, to avoid an issue with nest when one IIO
    device is the consumer of another.
  * White space tweaks.
- asc,dlhl60d
  * Use get_unaligned_be24 to avoid some unusual data manipulation and masking.
- atmel,at91-sama5d2
  * Fix wrong max value.
  * Improve error handling when measuring pressure and touch.
  * Add locks to remove races on updating oversampling / sampling freq.
  * Add missing calls in suspend and resume path to ensure state is correctly
    brought up if buffered capture was in use when suspend happened.
  * Error out of write_raw() callback if buffered capture enabled to avoid
    unpredictable behavior.
  * Handle different versions having different oversampling ratio support and
    drop excess error checking.
  * Cleanup magic value defines where the name is just the value and hence
    hurts readability.
  * Use read_avail() callback to provide info on possible oversampling ratios.
  * Correctly handle variable bit depth when doing oversampling on different
    supported parts. Also handle higher oversampling ratios.
- fsl,imx8qxp
  * Don't ignore errors from regulator_get_voltage() so as to avoid some
    very surprising scaling.
- invensense,icp10100
  * Switch from UNIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS. UNIVERSAL rarely made
    sense and is now deprecated. In this driver we just avoid double disabling
    in some paths.
- maxim,max1363
  * Drop consumer channel map provision by platform data. There have been
    better ways of doing this for years and there are no in tree users.
- microchip,mcp3911
  * Update status to maintained.
- qcom,spmi-adc5
  * Support measurement of LDO output voltage.
- qcom,spmi-adc
  * Add missing channel available on SM6125 SoC.
- st,stmpe
  * Drop requirement on node name in binding now that driver correctly
    doesn't enforce it.
- stx104
  * Move to more appropriate addac directory
- ti,am335x
  * Document ti,am654-adc compatible already in use in tree.
- ti,hmc5843
  * Move dev_pm_ops out of header and use new pm macros to handle export.
- yamaha,yas530
  * Minor cleanups.

+  The RTQ6056 is a high accuracy current-sense monitor with I2C and SMBus

+  The device monitors both of the drops across sense resistor and the BUS
+  voltage, converts into the current in amperes, and power in watts through
