[Feature] Skylake audio support (HD/HDMI/DP audio)

Do we have references for the upstream commits for this?

Hui will work on this, thanks ;)

powerwell support for HDMI/DP audio will be included in the next pull request for i915_bpo

sorry, wrong bug

Hi Xiong, do we have a list of commits for this that we should confirm we have included in Wily 15.10? Thanks.

I don't have a commits list for this, but it could work on Wily 15.10.
But you should back port the following patches to support HDMI / DP hotplug
25adc13 ALSA: hda - Wake the codec up on pin/ELD notify events
45c053d ALSA: hda - allow codecs to access the i915 pin/ELD callback
51e1d83 drm/i915: Call audio pin/ELD notify function
2a8ceed drm/i915: Add audio pin sense / ELD callback

Hi Tim and thanks for taking care of it so far - for consistency, would you mind adding two more:

commit d5f362a7b977bdfaf8a955f3d604a29267bd5464
Author: David Henningsson <email address hidden>
Date: Thu Sep 3 11:51:35 2015 +0200

    drm/i915: Add locks around audio component bind/unbind

And:

commit f0675d4a8ed9d3e863ff611561ee0944969a2784
Author: David Henningsson <email address hidden>
Date: Thu Sep 3 11:51:34 2015 +0200

    drm/i915: Drop port_mst_index parameter from pin/eld callback

....that brings us more in line with both 4.3 as well as in 3.19. (Because upstream made a mistake, the four patches we have in 3.19 corresponds to the six pointed out by Xiong and me.)

Just adding a note here that Tim picked up the additional two patches requested by David in comment #6. There are in the 4.2.0-12.14 kernel currently in wily-proposed. Thanks.

This bug was fixed in the package linux - 4.2.0-12.14
