From 56b4437f15ed2003413b857e08740576332e72d7 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Mon, 23 Nov 2015 21:22:30 +0530 Subject: ASoC: dapm: add a dapm sink widget 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 --- include/sound/soc-dapm.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/sound') diff --git a/include/sound/soc-dapm.h b/include/sound/soc-dapm.h index 7855cfe46b69..fe19dd3abb00 100644 --- a/include/sound/soc-dapm.h +++ b/include/sound/soc-dapm.h @@ -49,6 +49,9 @@ struct device; #define SND_SOC_DAPM_SIGGEN(wname) \ { .id = snd_soc_dapm_siggen, .name = wname, .kcontrol_news = NULL, \ .num_kcontrols = 0, .reg = SND_SOC_NOPM } +#define SND_SOC_DAPM_SINK(wname) \ +{ .id = snd_soc_dapm_sink, .name = wname, .kcontrol_news = NULL, \ + .num_kcontrols = 0, .reg = SND_SOC_NOPM } #define SND_SOC_DAPM_INPUT(wname) \ { .id = snd_soc_dapm_input, .name = wname, .kcontrol_news = NULL, \ .num_kcontrols = 0, .reg = SND_SOC_NOPM } @@ -484,6 +487,7 @@ enum snd_soc_dapm_type { snd_soc_dapm_aif_in, /* audio interface input */ snd_soc_dapm_aif_out, /* audio interface output */ snd_soc_dapm_siggen, /* signal generator */ + snd_soc_dapm_sink, snd_soc_dapm_dai_in, /* link to DAI structure */ snd_soc_dapm_dai_out, snd_soc_dapm_dai_link, /* link between two DAI structures */ -- cgit v1.2.3-55-g7522
