[PATCH v1 1/2] dt-bindings: sound: convert rockchip i2s bindings to yaml

[PATCH v1 1/2] dt-bindings: sound: convert rockchip i2s bindings to yaml

[Johan Jonker]

Current dts files with 'i2s' nodes are manually verified.
In order to automate this process rockchip-i2s.txt
has to be converted to yaml.

[PATCH v1 2/2] dt-bindings: sound: rockchip-i2s: add #sound-dai-cells property

[Johan Jonker]

'#sound-dai-cells' is required to properly interpret
the list of DAI specified in the 'sound-dai' property,
so add them to 'rockchip-i2s.yaml'
