Subject: [PATCH v2] ASoC: dt-bindings: cirrus,cs4270: Convert to dtschema
Convert the Cirrus Logic CS4270 audio CODEC bindings to DT schema. Add
missing va-supply, vd-supply and vlc-supply properties, because they
are already being used in the DTS and the driver for this device.
Cc: Daniel Baluta <daniel.baluta@....com>
Signed-off-by: Animesh Agarwal <animeshagarwal28@...il.com>

Changes in v2:
- Added proper description for power supply properties.
- Added ref to dai-common.
- Added '#sound-dai-cells'.
- Dropped unused labels in example.
- Replaced example node name to a generic name.
