1Bindings for Linear Technologies LT3593 LED controller 2 3Required properties: 4- compatible: Should be "lltc,lt3593". 5- lltc,ctrl-gpios: A handle to the GPIO that is connected to the 'CTRL' 6 pin of the chip. 7 8The hardware supports only one LED. The properties of this LED are 9configured in a sub-node in the device node. 10 11Optional sub-node properties: 12- label: A label for the LED. If none is given, the LED will be 13 named "lt3595::". 14- linux,default-trigger: The default trigger for the LED. 15 See Documentation/devicetree/bindings/leds/common.txt 16- default-state: The initial state of the LED. 17 See Documentation/devicetree/bindings/leds/common.txt 18 19If multiple chips of this type are found in a design, each one needs to 20be handled by its own device node. 21 22Example: 23 24led-controller { 25 compatible = "lltc,lt3593"; 26 lltc,ctrl-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>; 27 28 led { 29 label = "white:backlight"; 30 default-state = "on"; 31 }; 32}; 33
