Subject: [GIT PULL] Add get_eld audio component for i915/HD-audio
Date: Thu, 10 Dec 2015 14:16:03 +0100 [thread overview]
Message-ID: <s5hmvtimoks.wl-tiwai@suse.de> (raw)
Hi Daniel,
please pull the get_eld op addition from:
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git tags/drm-i915-get-eld
The topmost commit is 0bdf5a05647a66dcc6394986e061daeac9b1cf96
----------------------------------------------------------------
Add get_eld audio component for i915/HD-audio
Here are the 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; namely, the audio driver may fetch
directly the audio status and ELD via the new component op.
The commits are based on Dave's latest drm-next branch.
