+Required properties:
+- compatible: "allwinner,sun4i-a10-can"

+Example
+-------
+
+SoC common .dtsi file:
+
+ can0_pins_a: can0@0 {
+ allwinner,pins = "PH20","PH21";
+ allwinner,function = "can";
+ allwinner,drive = <0>;
+ allwinner,pull = <0>;
+ };
+...
+ can0: can@01c2bc00 {
+ compatible = "allwinner,sun4i-a10-can";
+ reg = <0x01c2bc00 0x400>;
+ interrupts = <0 26 4>;
+ clocks = <&apb1_gates 4>;
+ status = "disabled";
+ };
+
+Board specific .dts file:
+
+ can0: can@01c2bc00 {
+ pinctrl-names = "default";
+ pinctrl-0 = <&can0_pins_a>;
+ status = "okay";
+ };
