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" Kiran Gunda (3): backlight: qcom-wled: convert the wled bindings to .yaml format backlight: qcom-wled: Add callback functions backlight: qcom-wled: Add WLED5 bindings Subbaraman Narayanamurthy (1): backlight: qcom-wled: Add support for WLED5 peripheral that is present on PM8150L PMICs .../bindings/leds/backlight/qcom-wled.txt | 154 ----- .../bindings/leds/backlight/qcom-wled.yaml | 255 ++++++++ drivers/video/backlight/qcom-wled.c | 659 ++++++++++++++++++--- 3 files changed, 841 insertions(+), 227 deletions(-) delete mode 100644 Documentation/devicetree/bindings/leds/backlight/qcom-wled.txt create mode 100644 Documentation/devicetree/bindings/leds/backlight/qcom-wled.yaml
