-LEDs connected to Spreadtrum SC27XX PMIC breathing light controller
-
-The SC27xx breathing light controller supports to 3 outputs:
-red LED, green LED and blue LED. Each LED can work at normal
-PWM mode or breath light mode.
-
-Required properties:
-- compatible: Should be "sprd,sc2731-bltc".
-- #address-cells: Must be 1.
-- #size-cells: Must be 0.
-- reg: Specify the controller address.
-
-Required child properties:
-- reg: Port this LED is connected to.
-
-Optional child properties:
-- function: See Documentation/devicetree/bindings/leds/common.txt.
-- color: See Documentation/devicetree/bindings/leds/common.txt.
-- label: See Documentation/devicetree/bindings/leds/common.txt (deprecated).
