[alsa-devel] [RFC 2/5] ASoC multi-component support : DAPM
Liam Girdwood
lrg at slimlogic.co.uk
Thu Jun 24 21:24:38 CEST 2010
This patch adds DAPM support for ASoC multi-component and removes struct
snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
or runtime PCM level basis rather than using snd_soc_socdev.
Also added void snd_soc_dapm_shutdown() to shutdown all CODECs in a card.
