Subject: [PATCH V6 0/4] Add support for WLED5

Currently, WLED driver supports only WLED4 peripherals that is present
on pmi8998 and pm660L. This patch series  converts the existing WLED4
bindings from .txt to .yaml format and adds the support for WLED5 peripheral
that is present on PM8150L.

PM8150L WLED supports the following.
    - Two modulators and each sink can use any of the modulator
    - Multiple CABC selection options
    - Multiple brightness width selection (12 bits to 15 bits)

Changes from V1:
	- Rebased on top of the below commit.
	  backlight: qcom-wled: Fix unsigned comparison to zero

Changes from V2:
	- Addressed Bjorn's comments by splitting the WLED4 changes
	  in a seperate patch.
	- Added WLED5 auto calibration support

Changes from V3:
        - Addressed comments from Daniel Thompson and Rob Herring
        - Seperated the WLED5 bindings from the driver changes
         - Squashed wled5 auto string detection and wled5 basic changes
          to avoid the NULL callback function pointer issue.

Changes from V4:
        - Addressed the yaml formatting comments from Rob Herring.
        - Addressed the comments from Daniel Thompson on the below patch
  	  "backlight: qcom-wled: Add callback functions"

Changes from V5:
        - This series depends on the below patch.
          https://lore.kernel.org/patchwork/patch/1226258/
        - Addressed yaml formatting comments from Rob Herring.
        - Removed the "wled_ovp_fault_status" callback as per Daniel Thomson
          suggestion from patch #2.
        - Addressed comments from Daniel Thomson on patch #4.
