dt-bindings: leds: Add bindings for lltc,lt3593 (f041f96a) · Commits · 戴 / test

This patch adds the bindings document for LT3593 LED drivers. The binding is kept consistent with other LED driver bindings in that it stores all the LED-specific properties in its own subnode. As the hardware only supports one channel, there can consequently only be one sub-node. Signed-off-by:

		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:
		- label: A label for the LED. If none is given, the LED will be
		named "lt3595::".
		- 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:

		led-controller {
		compatible = "lltc,lt3593";
		lltc,ctrl-gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;

		led {
		label = "white:backlight";
		default-state = "on";
		};
		};
