Hi,
This patch is proposed as a result of a previous discussion related to include audio support in the DSS device driver (http://www.spinics.net/lists/linux-omap/msg64748.html)
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).
BR,
Ricardo
