20 -----------
25 GPIOs mappings are defined in the consumer device's node, in a property named
26 <function>-gpios, where <function> is the function the driver will request
32 led-gpios = <&gpio 15 GPIO_ACTIVE_HIGH>, /* red */
36 power-gpios = <&gpio 1 GPIO_ACTIVE_LOW>;
39 Properties named <function>-gpio are also considered valid and old bindings use
48 red = gpiod_get_index(dev, "led", 0, GPIOD_OUT_HIGH);
49 green = gpiod_get_index(dev, "led", 1, GPIOD_OUT_HIGH);
