[alsa-devel] [PATCH 0/7] Add get_eld audio component for i915/HD-audio

[Takashi Iwai]

Hi,

this is a patchset to add get_eld op to audio component for
communicating more directly between i915 and HD-audio.  Currently, the
HDMI/DP audio status and ELD are notified and obtained via the
hardware-level communication over HD-audio unsolicited event and
verbs although the graphics driver holds the exactly same
information.  As we already have a notification via audio component,
this is another step forward; the audio driver fetches directly the
audio status and ELD via the new component op.

The initial draft was posted to alsa-devel as an RFC some weeks ago,
and this is a revised version, posted to both i915 and alsa-devel for
review.

The current patchset is found in sound git tree test/hdmi-jack
branch.
