| | | | | | | | | | | Now that we have the bus parse capabilities moved to core, we need to convert users. The SKL driver and HDA extended lib needs to converted in single patch, otherwise we regress on the functionality.

| * ALSA: hdac: add link pm and ref countingVinod Koul2016-05-132-0/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HDA links can be switched off when not is use, similarly command DMA can be stopped as well. This calls for a reference counting mechanism on the link by it's users to manage the link power. The DMA can be turned off when all links are off For this we add two APIs snd_hdac_ext_bus_link_get snd_hdac_ext_bus_link_put They help users to turn up/down link and manage the DMA as well Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
