2017-06-30T10:55:20Z

Add some DAPM widget types to better support the construction of DAPM graphs within DSPs. Signed-off-by: Liam Girdwood Signed-off-by: Mark Brown

ASoC: dapm: Introduce DAPM_DOUBLE_R dual channel dual register control type

2016-11-02T15:55:30Z

A DAPM_DOUBLE_R control type can be used for dual channel mixer input selectors / mute controls across 2 registers, possibly toggling both channels together. The control is meant to be shared by 2 widgets, 1 for each channel, such that the mixer control exposed to userspace remains a combined stereo control.

ASoC: dapm: Support second register for DAPM control updates

2016-11-02T15:55:03Z

To support double channel shared controls split across 2 registers, one for each channel, we must be able to update both registers together. Add a second set of register fields to struct snd_soc_dapm_update, and update the DAPM control writeback (put) callbacks to support this. For codecs that use custom events which call into DAPM to do updates, also clear struct snd_soc_dapm_update before using it, so the second set of fields remains clean.

ASoC: dapm: Export snd_soc_dapm_new_control

This is useful outside the core, when one dapm element is added at a time. Signed-off-by: Subhransu S. Prusty Signed-off-by: Vinod Koul Signed-off-by: Mark Brown

ASoC: dapm: support user-defined stop condition in dai_get_connected_widgets

2016-05-30T15:15:10Z

Certain situations may warrant examining DAPM paths only to a certain arbitrary point, as opposed to always following them to the end. For instance, when establishing a connection between a front-end DAI link and a back-end DAI link in a DPCM path, it does not make sense to walk the DAPM graph beyond the first widget associated with a back-end link. This patch introduces a mechanism which lets a user of dai_get_connected_widgets supply a function which will be called for every node during the graph walk. When invoked, this function can execute arbitrary logic to decide whether the walk, given a DAPM widget and walk direction, should be terminated at that point or continued as normal.

ASoC: dapm: deprecate MICBIAS widget type

2016-05-12T14:01:08Z

Commit 086d7f804e26 ("ASoC: Convert WM8962 MICBIAS to a supply widget", 2011-09-23) says: A supply widget is generally clearer than a MICBIAS widget and a mic bias is just a type of supply so use a supply widget for the MICBIAS. This also avoids confusion with the routing when connected to multiple inputs. but this has never been documented as a policy. Add some comments to make it clear.

ASoC: dapm: add a dapm sink widget

2015-11-25T12:55:37Z

DAPM models various widgets but lacks a sink widget. DSPs can have modules which take audio data, process it and are capable of generating events thus acting as a sink of data. To make the dapm graph complete for such paths we need a dapm sink widget for these modules, so add a SND_SOC_DAPM_SINK to declare such a widget. This widget will be treated as SND_SOC_DAPM_EP_SINK endpoint in the dapm graph Signed-off-by: Vinod Koul Reviewed-by: Lars-Peter Clausen Signed-off-by: Mark Brown
