比如 sun8i-v3s-licheepi-zero.dts
&ohci0 {
status = "okay";
};&uart0 {
pinctrl-0 = <&uart0_pins_a>;
pinctrl-names = "default";
status = "okay";
};&uart1 {
pinctrl-0 = <&uart1_pins_a>;
pinctrl-names = "default";
status = "okay";
};&uart2 {
pinctrl-0 = <&uart2_pins_a>;
pinctrl-names = "default";
status = "okay";
};&usb_otg {
dr_mode = "otg";
status = "okay";
};
就是上面这个 okay 和 & 没搞明白.
