Subject: [PATCH v2] ASoC: dt-bindings: rockchip,rk3036-codec: convert to yaml
Convert the binding to yaml.
The codec seems to be from Innosilicon, but the compatible has ever only
been rockchip-based, as they sythesized the codec for the rk3036.
So the yaml file gets a name matching that compatible.
The only other notable change is the addition of the #sound-dai-cells
property, that is always required.

-Inno audio codec for RK3036
-
-Inno audio codec is integrated inside RK3036 SoC.
-
-Required properties:
-- compatible : Should be "rockchip,rk3036-codec".
-- reg : The registers of codec.
-- clock-names : Should be "acodec_pclk".
-- clocks : The clock of codec.
-- rockchip,grf : The phandle of grf device node.
-
-Example:
-
- acodec: acodec-ana@...30000 {
- compatible = "rk3036-codec";
- reg = <0x20030000 0x4000>;
- rockchip,grf = <&grf>;
- clock-names = "acodec_pclk";
- clocks = <&cru ACLK_VCODEC>;
- };
