Examples for writing led driver on MYS-6ULX-IND single board computer
 
Question
I want to write a led driver based on MYS-6ULX-IND single board computer, but I don’t know how to configure mys-imx6ul-14x14-evk.dts, are there any examples for reference?
Answer
You can refer to the configuration of leds on mys-imx6ul-14x14-evk.dts, pinctrl_leds is the configuration of pinmux.

       leds {

              compatible = "gpio-leds";

              pinctrl-names = "default";

              pinctrl-0 = <&pinctrl_leds>;

        

              led0: cpu {

                       label = "user";

                       gpios = <&gpio5 1 GPIO_ACTIVE_LOW>;

                       default-state = "off";

           };

         

              led1: user {

                      label = "cpu";

                      gpios = <&gpio5 2 GPIO_ACTIVE_LOW>;

                      default-state = "on";

                      linux,default-trigger = "heartbeat";
           };
       };
