Kernel-4.18.0-80.el8_allwinner,sun4i-ps2

• 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>;
};
