[Intel-gfx] [PATCH v4 0/4] i915 to call hda driver on HDMI plug/unplug

[David Henningsson]

It's been a while since the last patch set iteration, due to me
being on vacation. But here's a new set, and I still hope that it can
make it into the next merge window.

Changes since v3 (with the person suggesting that change within parantheses):
 * Valleyview now has three pins like all the others (Libin Yang)
 * Renamed a few references from "hotplug" to "pin_eld" to reduce 
   confusion with hotplug code on the i915 side (Jani Nikula)
 * Rewrote the dispatching from hda core to codec on the hda side (Takashi Iwai)

This iteration has been tested and working on one Skylake machine.

David Henningsson (4):
  drm/i915: Add audio pin sense / ELD callback
  drm/i915: Call audio pin/ELD notify function
  ALSA: hda - allow codecs to access the i915 pin/ELD callback
  ALSA: hda - Wake the codec up on pin/ELD notify events
