*	drm/i915/audio: add codec wakeup override enabled/disable callback	Lu, Han	2015-05-05	1	-0/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	drm/i915: add component support	Imre Deak	2015-01-12	1	-0/+38
	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) Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
