)

snd_soc_dapm_put_value_enum_double - dapm semi enumerated double mixer set callback : mixer control : control element information

Callback to set the value of a dapm semi enumerated double mixer control.

Semi enumerated mixer: the enumerated items are referred as values. Can be used for handling bitfield coded enumeration for example.

Returns 0 for success.

snd_soc_dapm_stream_event - send a stream event to the dapm core : PCM runtime data : stream name : stream event

Sends a stream event to the dapm core. The core then makes any necessary widget power changes.

Returns 0 for success else error.

int snd_soc_dapm_weak_routes ( struct snd_soc_dapm_context *  dapm,
const struct snd_soc_dapm_route *  route,
int  num 
)

snd_soc_dapm_weak_routes - Mark routes between DAPM widgets as weak : DAPM context : audio routes : number of routes

Mark existing routes matching those specified in the passed array as being weak, meaning that they are ignored for the purpose of power decisions. The main intended use case is for sidetone paths which couple audio between other independent paths if they are both active in order to make the combination work better at the user level but which aren't intended to be "used".

Note that CODEC drivers should not use this as sidetone type paths can frequently also be used as bypass paths.
