+Allwinner A10/A20 CAN controller Device Tree Bindings
+-

+Required properties:
+- compatible: "allwinner,sun4ican"
+- reg: physical base address and size of the Allwinner A10/A20 CAN register 
map.
+- interrupts: interrupt specifier for the sole interrupt.
+- clock: phandle and clock specifier.

+Example

+
+SoC common .dtsi file:
+
+   can0_pins_a: can0@0 {
+   allwinner,pins = "PH20","PH21";
+   allwinner,function = "can";
+   allwinner,drive = <0>;

+   interrupts = <0 26 4>;
+   clocks = <_gates 4>;
+   status = "disabled";
+   };
+
+Board specific .dts file:
+
+   can0: can@01c2bc00 {
+   pinctrl-names = "default";

+   status = "okay";
