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.
