This patch is proposed as a result of a previous discussion related to
include audio support in the DSS device driver
At the moment, this is intended to cover display technologies with audio based
on CEA-861 and IEC-60958, such as HDMI and DisplayPort. However, provisions are
made to make it extensible (see below).
These are the changes with respect to v2:
* A new enum and field is added to DSS to help implementations of the interface
to keep track of the audio state.
These are the changes with respect to v1:
* The audio_enable and audio_start functions were split into enable/disable
and start/stop respectively to improve readability.
* Comments were added on whether the DSS audio functions may sleep.
* In order to make the audio configuration parameters extensible, a
struct omap_dss_audio is defined. This helps to easily add more config
parameters in the future if/when required (e.g., speaker order configuration).
