-LEDs connected to GPIO lines
-
-Required properties:
-- compatible : should be "gpio-leds".
-
-Each LED is represented as a sub-node of the gpio-leds device. Each
-node's name represents the name of the corresponding LED.
-
-LED sub-node properties:
-- gpios : Should specify the LED's GPIO, see "gpios property" in
- Documentation/devicetree/bindings/gpio/gpio.txt. Active low LEDs should be
- indicated using flags in the GPIO specifier.
-- label : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-- linux,default-trigger : (optional)
- see Documentation/devicetree/bindings/leds/common.txt
-- default-state: (optional) The initial state of the LED. Valid
- values are "on", "off", and "keep". If the LED is already on or off
- and the default-state property is set the to same value, then no
- glitch should be produced where the LED momentarily turns off (or
- on). The "keep" setting will keep the LED at whatever its current
- state is, without producing a glitch. The default is off if this
- property is not present.
-
-Examples:
-
-leds {
- compatible = "gpio-leds";
- hdd {
- label = "IDE Activity";
- gpios = <&mcu_pio 0 1>; /* Active low */
- linux,default-trigger = "ide-disk";
- };
-
- fault {
- gpios = <&mcu_pio 1 0>;
- /* Keep LED on if BIOS detected hardware fault */
- default-state = "keep";
- };
-};
-
-run-control {
- compatible = "gpio-leds";
- red {
- gpios = <&mpc8572 6 0>;
- default-state = "off";
- };
- green {
- gpios = <&mpc8572 7 0>;
- default-state = "on";
- };
-};
