Merge tag 'iio-for-5.15b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

2nd set of new IIO device support and cleanups for the 5.15 cycle.

A small pull request to pick up a few new drivers and some cleanup
and fix patches.

New device support
* ad5110 non-volatile digital potentiometer
  - New driver
* renesas rzl/gl2 12-bit / 8 channel ADC block
  - New driver and bindings

Minor or late breaking fixes and cleanups
* ltc2983
  - Fix a false assumption of initial interrupt during probe().
* hp03
  - Use devm_* to simplify probe and allow the remove function to be dropped.
* rockchip_saradc
  - Use a regulator notifier to reduce overheads of querying the scale.

* tag 'iio-for-5.15b' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio:
  iio: adc: Add driver for Renesas RZ/G2L A/D converter
  dt-bindings: iio: adc: Add binding documentation for Renesas RZ/G2L A/D converter
  iio: pressure: hp03: update device probe to register with devm functions
  iio: adc: rockchip_saradc: add voltage notifier so get referenced voltage once at probe
  iio: ltc2983: fix device probe
  iio: potentiometer: Add driver support for AD5110
  dt-bindings: iio: potentiometer: Add AD5110 in trivial-devices

description: |

  A/D Converter block is a successive approximation analog-to-digital converter

  with a 12-bit accuracy. Up to eight analog input channels can be selected.

  Conversions can be performed in single or repeat mode. Result of the ADC is

  stored in a 32-bit data register corresponding to each channel.
