+* Device tree bindings for Allwinner A10, A20 PS2 host controller
+
+A20 PS2 is dual role controller(PS2 host and PS2 device). These bindings are for PS2 host controller.
+IBM compliant IBM PS2 and AT-compatible keyboard and mouse can be connected.
+
+Required properties:
+
+ - reg             : Offset and length of the register set for the device.
+ - compatible      : Should one of the following:
+                     - "allwinner,sun7i-a20-ps2"
+                     - "allwinner,sun4i-a10-ps2"
+ - interrupts      : The interrupt line connected to the PS2.
+ - clocks          : The gate clk connected to the PS2.
+
+
+Example:
+	ps20: ps2 at 0x01c2a000 {
+		compatible = "allwinner,sun7i-a20-ps2";
+		reg = <0x01c2a000 0x400>;
+		interrupts = <0 62 4>;
+		clocks = <&apb1_gates 6>;
+		status = "disabled";
+	};
