We reuse the trigger-sources phandle to just point to
GPIOs we may want to use as LED triggers.
Example:
gpio: gpio@0 {
compatible "my-gpio";
gpio-controller;
#gpio-cells = <2>;
interrupt-controller;
#interrupt-cells = <2>;
#trigger-source-cells = <2>;
};
leds {
compatible = "gpio-leds";
led-my-gpio {
label = "device:blue:myled";
gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;
default-state = "off";
linux,default-trigger = "gpio";
trigger-sources = <&gpio 1 GPIO_ACTIVE_HIGH>;
};
};
