Excerpt

<div>I am working with a imx6ull custom board. Was there a way to specify trigger parameters in the devicetree? For example I'll like gpio 122 to trigger the led to blink. Current DT: leds { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_led>; compatible = "gpio-leds"; led_wwan { label = "led_wwan";</div>
