-Qualcomm PM8058 LED driver
-
-The Qualcomm PM8058 is a multi-functional device which contains
-an LED driver block for up to six LEDs: three normal LEDs, two
-"flash" LEDs and one "keypad backlight" LED. The names are
-quoted because sometimes these LED drivers are used for wildly
-different things than flash or keypad backlight: their names
-are more of a suggestion than a hard-wired usecase.
-
-Hardware-wise the different LEDs support slightly different
-output currents. The "flash" LEDs do not need to charge nor
-do they support external triggers. They are just powerful LED
-drivers.
-
-The LEDs appear as children to the PM8058 device, with the
-proper compatible string. For the PM8058 bindings see:
-mfd/qcom-pm8xxx.txt.
-
-Each LED is represented as a sub-node of the syscon device. Each
-node's name represents the name of the corresponding LED.
-
-LED sub-node properties:
-
-Required properties:
-- compatible: one of
- "qcom,pm8058-led" (for the normal LEDs at 0x131, 0x132 and 0x133)
- "qcom,pm8058-keypad-led" (for the "keypad" LED at 0x48)
- "qcom,pm8058-flash-led" (for the "flash" LEDs at 0x49 and 0xFB)
-
-Optional properties:
-- label: see Documentation/devicetree/bindings/leds/common.txt
-- default-state: see Documentation/devicetree/bindings/leds/common.txt
-- linux,default-trigger: see Documentation/devicetree/bindings/leds/common.txt
-
-Example:
-
-qcom,ssbi@500000 {
- pmicintc: pmic@0 {
- compatible = "qcom,pm8058";
- led@48 {
- compatible = "qcom,pm8058-keypad-led";
