rk3328-roc-cc 如何将gpio 注册至leds-gpio驱动框架下 其dts文件如何编写

panzidong

修改kernel/arch/arm64/boot/dts/rockchip/rk3328-roc-cc.dts
将系统自带的   ir leds打开编译，出现如下错误，           
  ir {
                        status = "disabled";
                        gpios = <&gpio2 GPIO_C2 GPIO_ACTIVE_HIGH>;
                        linux,default-trigger = "ir";
                        default-state = "off";
                        mode = <0x00>;
                };

make[1]: 'include/generated/vdso-offsets.h' is up to date.
  CHK     include/generated/compile.h
