-Allwinner A10/A20 CAN controller Device Tree Bindings
------------------------------------------------------
-
-Required properties:
-- compatible: "allwinner,sun4i-a10-can"
-- 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>;
-		allwinner,pull = <0>;
-	};
-...
-	can0: can@1c2bc00 {
-		compatible = "allwinner,sun4i-a10-can";
-		reg = <0x01c2bc00 0x400>;
-		interrupts = <0 26 4>;
-		clocks = <&apb1_gates 4>;
-		status = "disabled";
-	};
-
-Board specific .dts file:
-
-	can0: can@1c2bc00 {
-		pinctrl-names = "default";
-		pinctrl-0 = <&can0_pins_a>;
-		status = "okay";
-	};
