David Henningsson f0675d4a8e drm/i915: Drop port_mst_index parameter from pin/eld callback
The port_mst_index parameter was reserved for future use, but
maintainers prefer to add it later when it is actually used.

[Note: this is an update patch to commit [51e1d83cab99: drm/i915: Call
 audio pin/ELD notify function] where I mistakenly applied the older
 version.  Jani and Daniel's review tags were to the latest version,
 so I add them below, too -- tiwai]

David Henningsson 2a8ceedf78 drm/i915: Add audio pin sense / ELD callback
This callback will be called by the i915 driver to notify the hda
driver that its HDMI information needs to be refreshed, i e,
that audio output is now available (or unavailable) - usually as a
result of a monitor being plugged in (or unplugged).

Lu, Han 632f3ab95f drm/i915/audio: add codec wakeup override enabled/disable callback
Add support for enabling codec wakeup override signal to allow
re-enumeration of the controller on SKL after resume from low power state.

In SKL, HDMI/DP codec and PCH HD Audio Controller are in different power
wells, so it's necessary to reset display audio codecs when power well on,
otherwise display audio codecs will disappear when resume from low power
state.
Reset steps when power on:
    enable codec wakeup -> azx_init_chip() -> disable codec wakeup

v3 by Jani: Simplify to only support toggling the appropriate chicken bit.

v4 by Han: add explanation and specify the hw swquence.

Imre Deak 58fddc288b drm/i915: add component support
Register a component to be used to interface with the snd_hda_intel
driver. This is meant to replace the same interface that is currently
based on module symbol lookup.

v2:
- change roles between the hda and i915 components (Daniel)
- add the implementation to a new file (Jani)
- use better namespacing (Jani)
v3:
- move the implementation to intel_audio.c (Daniel)
- rename display_component to audio_component (Daniel)
- add kerneldoc (Daniel)
v4:
- run forgotten git rm i915_component.c (Jani)
