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- function: See Documentation/devicetree/bindings/leds/common.txt 13- color: See Documentation/devicetree/bindings/leds/common.txt 14- label: A label for the LED. If none is given, the LED will be 15 named "lt3595::" (deprecated) 16- linux,default-trigger: The default trigger for the LED. 17 See Documentation/devicetree/bindings/leds/common.txt 18- default-state: The initial state of the LED. 19 See Documentation/devicetree/bindings/leds/common.txt 20 21If multiple chips of this type are found in a design, each one needs to 22be handled by its own device node. 23 24Example: 25 26#include <dt-bindings/leds/common.h> 27 28led-controller { 29 compatible = "lltc,lt3593"; 30 lltc,ctrl-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>; 31 32 led { 33 function = LED_FUNCTION_BACKLIGHT; 34 color = <LED_COLOR_ID_WHITE>; 35 default-state = "on"; 36 }; 37}; 38
