1 Bindings for Linear Technologies LT3593 LED controller
2
3 Required 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
8 The hardware supports only one LED. The properties of this LED are
9 configured in a sub-node in the device node.
10
11 Optional 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
21 If multiple chips of this type are found in a design, each one needs to
22 be handled by its own device node.

24 Example:
25
26 #include <dt-bindings/leds/common.h>
27
28 led-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 };
