[GIT PULL] Add get_eld audio component for i915/HD-audio

[Takashi Iwai]

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.

      drm/i915: Add get_eld audio component
      drm/i915: Add reverse mapping between port and intel_encoder

Daniel, would you pull this one, or should we postpone it for 4.6?
The changes aren't too intrusive, so I prefer having it for 4.5, so
that we can continue developing the MST audio stuff based on this.


thanks,

Takashi

Sorry, simply for got send out the confirmation mail. I pulled this a few
days ago already and will send the final drm-intel pull for 4.5 with it to
Dave soonish.

Thanks, Daniel

Great, that's a good news.  Then I'll merge the branch and the commits
on its top to sound git tree, too.

Thanks!
