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.
