One more patch to add support in codec will follow this The aim of serial is to shut down the links when not in use and keep them active when a user is active. The user can activate link by taking reference to the link when required. When all links are shutdown, the command DMAs are turned off as well. On first link power up, the command DMAs are turned on first. First patch touches HDA core, and second one is dependent on it so Takashi if you are okay, pls ACK it and we cna merge thru ASoC tree Vinod Koul (2): ALSA: hdac: add link pm and ref counting ASoC: Intel: Skylake: add link mangement include/sound/hdaudio_ext.h | 13 ++++++++ sound/hda/ext/hdac_ext_bus.c | 3 ++ sound/hda/ext/hdac_ext_controller.c | 62 +++++++++++++++++++++++++++++++++++++ sound/soc/intel/skylake/skl-pcm.c | 1 - sound/soc/intel/skylake/skl.c | 34 ++++++++++++++++++++ 5 files changed, 112 insertions(+), 1 deletion(-) -- 1.9.1
