so I guess this hdmi_audio code goes on top of >= 4.5 kernel series (current mainline),
not as the https://github.com/plbossart/sound/commits/baytrail-stick-rebase-4.4
Beside https://lists.freedesktop.org/archives/intel-gfx/
and https://patchwork.freedesktop.org/project/intel-gfx/
is there a branch at https://cgit.freedesktop.org/drm-intel/
or a repo at https://git.kernel.org/cgit/ in which this hdmi_audio code exists?
