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.

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};
