omapdss driver support for audio
|
||||
--------------------------------
|
||||
There exist several display technologies and standards that support audio as
|
||||
well. Hence, it is relevant to update the DSS device driver to provide an audio
|
||||
interface that may be used by an audio driver or any other driver interested in
|
||||
the functionality.
|
||||
|
||||
The audio_enable function is intended to prepare the relevant
|
||||
IP for playback (e.g., enabling an audio FIFO, taking in/out of reset
|
||||
some IP, enabling companion chips, etc). It is intended to be called before
|
||||
audio_start. The audio_disable function performs the reverse operation and is
|
||||
intended to be called after audio_stop.
|
||||
|
||||
While a given DSS device driver may support audio, it is possible that for
|
||||
certain configurations audio is not supported (e.g., an HDMI display using a
|
||||
VESA video timing). The audio_supported function is intended to query whether
|
||||
the current configuration of the display supports audio.
|
||||
|
||||
The audio_config function is intended to configure all the relevant audio
|
||||
parameters of the display. In order to make the function independent of any
|
||||
specific DSS device driver, a struct omap_dss_audio is defined. Its purpose
|
||||
is to contain all the required parameters for audio configuration. At the
|
||||
moment, such structure contains pointers to IEC-60958 channel status word
|
||||
and CEA-861 audio infoframe structures. This should be enough to support
|
||||
HDMI and DisplayPort, as both are based on CEA-861 and IEC-60958.
|
||||
|
||||
The audio_enable/disable, audio_config and audio_supported functions could be
|
||||
implemented as functions that may sleep. Hence, they should not be called
|
||||
while holding a spinlock or a readlock.
|
||||
|
||||
The audio_start/audio_stop function is intended to effectively start/stop audio
|
||||
playback after the configuration has taken place. These functions are designed
|
||||
to be used in an atomic context. Hence, audio_start should return quickly and be
|
||||
called only after all the needed resources for audio playback (audio FIFOs,
|
||||
DMA channels, companion chips, etc) have been enabled to begin data transfers.
|
||||
audio_stop is designed to only stop the audio transfers. The resources used
|
||||
for playback are released using audio_disable.
|
||||
|
||||
The enum omap_dss_audio_state may be used to help the implementations of
|
||||
the interface to keep track of the audio state. The initial state is _DISABLED;
|
||||
then, the state transitions to _CONFIGURED, and then, when it is ready to
|
||||
play audio, to _ENABLED. The state _PLAYING is used when the audio is being
|
||||
rendered.
