[alsa-devel] [PATCH v3 0/9] ASoC: hdac_hdmi: Add multichannel support

[Subhransu S. Prusty]

This series parses ELD to identify multichannel capability of the
sync, and uses HDA framework to programs codec's channel map
registers.

Channel map controls are registered in patch 8, with which user
can specify a specific channel order. chmap controls are
registered inside jack_init callback. As PCMs need to be
registered before registering chmap controls, jack_init call in
the machine driver is moved to late_probe instead of init
callback.

Skylake driver is modified and buffer size calculation is fixed
for multichannel support.

Please note, patch 2 adds a small macro to read channel counts
from cap bits in HDA headers. This needs Takashi's ack, so that
it can be merged through ASoC.

Patch 7 has dependency on commit#44fde3b ("ALSA: hda - Update
chmap tlv to report sink's capability) which is merged in
Takashi's tree.

As Takashi suggested Mark may pull Takashi's for-next branch
before applying this or may send a pull request, so that Takashi
pull's Mark's tree before applying these with Mark's ack.

Mark, please check how you want this to be merged.

Changes in v3:
	* As suggested, simplified channel calculation expression
	  in get channel helper
	* Removed condition in max channel assignment expression
