* 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@01c2a000 { compatible = "allwinner,sun4i-a10-ps2"; reg = <0x01c2a000 0x400>; interrupts = <0 62 4>; clocks = <&apb1_gates 6>; };
