* 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";
};
