The Allwinner SoCs have a PWM controller 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.

Anyone? Should I just go ahead and merge it through the sunxi tree?

-Allwinner sun4i and sun7i SoC PWM controller
-
-Required properties:
-  - compatible: should be one of:
-    - "allwinner,sun4i-a10-pwm"
-    - "allwinner,sun5i-a10s-pwm"
-    - "allwinner,sun5i-a13-pwm"

-    - "allwinner,sun50i-h5-pwm", "allwinner,sun5i-a13-pwm"
-  - reg: physical base address and length of the controller's registers
-  - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
-    the cells format.
-  - clocks: From common clock binding, handle to the parent clock.
-
-Example:
-
-	pwm: pwm@1c20e00 {
-		compatible = "allwinner,sun7i-a20-pwm";
-		reg = <0x01c20e00 0xc>;
-		clocks = <&osc24M>;
-		#pwm-cells = <3>;
