The older Allwinner SoCs have a PS2 controller that is supported in Linux,
with a matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-* 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>;
-	};
