media: dt-bindings: media: Convert Allwinner A10 IR to a schema 



The older Allwinner SoCs have a IR receiver 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 SUNXI IR controller found in sunXi SoC family



Required properties:

- compatible	    :

	"allwinner,sun4i-a10-ir"

	"allwinner,sun5i-a13-ir"

	"allwinner,sun6i-a31-ir"

	"allwinner,sun50i-a64-ir", "allwinner,sun6i-a31-ir"

	"allwinner,sun50i-h6-ir", "allwinner,sun6i-a31-ir"

- clocks	    : list of clock specifiers, corresponding to

		      entries in clock-names property;

- clock-names	    : should contain "apb" and "ir" entries;

- interrupts	    : should contain IR IRQ number;

- reg		    : should contain IO map address for IR.



Required properties since A31:

- resets	    : phandle + reset specifier pair



Optional properties:

- linux,rc-map-name: see rc.txt file in the same directory.

- clock-frequency  : IR Receiver clock frequency, in Hertz. Defaults to 8 MHz

		     if missing.



Example:



ir0: ir@1c21800 {

	compatible = "allwinner,sun4i-a10-ir";

	clocks = <&apb0_gates 6>, <&ir0_clk>;

	clock-names = "apb", "ir";

	clock-frequency = <3000000>;

	resets = <&apb0_rst 1>;

	interrupts = <0 5 1>;

	reg = <0x01C21800 0x40>;

	linux,rc-map-name = "rc-rc6-mce";
