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.

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};
