[alsa-devel] [PATCH 00/11] 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 and 4 adds small macros to read speaker
allocation from ELD and channel counts from cap bits respectively
in DRM and HDA headers.  We have CCed DRM folks here. Please ack
patch 1, so that we can have this series merged through sound
trees. Patch 3 needs Takashi's ack, so that it can be merged
through ASoC.

Patch 9 has dependency on commit#44fde3b ("ALSA: hda - Update
chmap tlv to report sink's capability) which is merged in
Takashi's tree.

So this may be merged in ASoC with Takashi's Ack and pulling in
changes from Takashi's tree or alternatively it can be directly
merged in Takashi's with Mark's Ack

Takashi/Mark, please decide how you guys want this to be merged.
