For HDMI audio to work OMAPDSS HDMI support should be
enabled.
The hdmi audio driver implements cpu-dai component using the
callbacks provided by OMAPDSS and registers the component
under DSS HDMI device. Omap-pcm is registered for platform
component also under DSS HDMI device. Dummy codec is used as
as codec component. The hdmi audio driver implements also
the card and registers it under its own platform device.
The device for the driver is registered by OMAPDSS hdmi
driver.
