+* 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 A10/A20 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 be as of the following:
+ - "allwinner,sun4i-a10-ps2"
+ - interrupts : The interrupt line connected to the PS2.
+ - clocks : The gate clk connected to the PS2.
+
+
+Example:
+ ps20: ps2@0x01c2a000 {
+ compatible = "allwinner,sun4i-a10-ps2";
+ reg = <0x01c2a000 0x400>;
+ interrupts = <0 62 4>;
+ clocks = <&apb1_gates 6>;
+ status = "disabled";
+ };
