Subject: [PATCH 2/2] dt-bindings: media: Convert Allwinner A10 IR to a schema

From: Maxime Ripard <maxime.ripard@...tlin.com>

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@...1800 {
-	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";
