2018-06-28ALSA: hdac: ext: add wait for codec to respond after link resetRakesh Ughreja1-0/+9
As per HDA spec section 4.3 - Codec Discovery, the software shall wait for atleast 521usec for codec to respond after link reset. With the multi-link capability each link is turned ON/OFF individually. Link controller drives reset signal when it is turned ON.

This patch renames all the variable instances of hdac_device with hdev to prepare the code base to remove the usage of hdac_ext_device data structures done in the following patches. Existing code uses hdev and hdac as variable names for hdac_device as well as hdac_ext_device, which creates confusion.

2016-05-13ALSA: hdac: add link pm and ref countingVinod Koul2-0/+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>
