Bindings for Linear Technologies LT3593 LED controller
Required properties:
- compatible: Should be "lltc,lt3593".
- lltc,ctrl-gpios: A handle to the GPIO that is connected to the 'CTRL'
pin of the chip.
The hardware supports only one LED. The properties of this LED are
configured in a sub-node in the device node.
Optional sub-node properties:
- function: See Documentation/devicetree/bindings/leds/common.txt
- color: See Documentation/devicetree/bindings/leds/common.txt
- label: A label for the LED. If none is given, the LED will be
named "lt3595::" (deprecated)
- linux,default-trigger: The default trigger for the LED.
See Documentation/devicetree/bindings/leds/common.txt
- default-state: The initial state of the LED.
See Documentation/devicetree/bindings/leds/common.txt
If multiple chips of this type are found in a design, each one needs to
be handled by its own device node.
Example:
#include <dt-bindings/leds/common.h>
led-controller {
compatible = "lltc,lt3593";
lltc,ctrl-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;
led {
function = LED_FUNCTION_BACKLIGHT;
color = <LED_COLOR_ID_WHITE>;
default-state = "on";
};
};
