Binding for Qualcomm PM8941 WLED driver
Required properties:
- compatible: should be "qcom,pm8941-wled"
- reg: slave address
Optional properties:
- label: The label for this led
See Documentation/devicetree/bindings/leds/common.txt
- linux,default-trigger: Default trigger assigned to the LED
See Documentation/devicetree/bindings/leds/common.txt

- qcom,cabc: bool; enable content adaptive backlight control
- qcom,ext-gen: bool; use externally generated modulator signal to dim
- qcom,current-limit: mA; per-string current limit; value from 0 to 25
default: 20mA
- qcom,current-boost-limit: mA; boost current limit; one of:
105, 385, 525, 805, 980, 1260, 1400, 1680
default: 805mA
- qcom,switching-freq: kHz; switching frequency; one of:
