This patch series adds support for AWINIC AW20036/AW20054/AW20072 LED
driver programmed via an I2C interface.

This driver supports following AW200XX features:
  - Individual 64-level DIM currents

Datasheet:
  aw20036 - https://www.awinic.com/en/productDetail/AW20036QNR#tech-docs
  aw20054 - https://www.awinic.com/en/productDetail/AW20054QNR#tech-docs
  aw20072 - https://www.awinic.com/en/productDetail/AW20072QNR#tech-docs

Add YAML dt-binding schema for AW200XX.

Changelog:
v4 -> v5:
  - Cosmetic changes (rename aw200xx_probe_dt() to aw200xx_probe_fw()
    and etc)

v3 -> v4:
  - Calculate the value of imax instead of retrieving it from a table
  - Cosmetic changes

v2 -> v3:
  - Update datasheet links
  - Make cosmetic changes as Andy suggested at [1]

v1 -> v2:
  - Remove the hardware pattern support (I will send a separate patch)
  - Support the 'led-max-microamp' property
