No, I mean that if you want to control the enable and disable of the output path you should implement a DAPM widget.
May I ask which driver file to add a new DAPM widget? Is it the bridge ic driver like it6505.c? Or is it linke the "SDB" added in this patch?
I would expect this to follow a similar pattern to everything else with hdmi-codec.c and have the actual ASoC stuff in there with a callback exposed to the rest of the world.
Yes, I should add a new set of events, such as:
enum { HDMI_CODEC_TRIGGER_EVENT_STOP, HDMI_CODEC_TRIGGER_EVENT_START, HDMI_CODEC_TRIGGER_EVENT_SUSPEND, HDMI_CODEC_TRIGGER_EVENT_RESUME, }
Then provide handles for these events in the it6505 driver. Am I right?
I'd expect more like on/off for a DAPM widget (the DAPM callbacks are pre/post on/off) but yes.
