Merge tag 'drm-intel-next-2014-11-07-fixups' of git://anongit.freedesktop.org/drm-intel into drm-next

- skl watermarks code (Damien, Vandana, Pradeep)
- reworked audio codec /eld handling code (Jani)
- rework the mmio_flip code to use the vblank evade logic and wait for rendering
  using the standard wait_seqno interface (Ander)
- skl forcewake support (Zhe Wang)
- refactor the chv interrupt code to use functions shared with vlv (Ville)
- prep work for different global gtt views (Tvrtko Ursulin)
- precompute the display PLL config before touching hw state (Ander)
- completely reworked panel power sequencer code for chv/vlv (Ville)
- pre work to split the plane update code into a prepare and commit phase
  (Gustavo Padovan)
- golden context for skl (Armin Reese)
- as usual tons of fixes and improvements all over

/**
* DOC: High Definition Audio over HDMI and Display Port
*
* The graphics and audio drivers together support High Definition Audio over
* HDMI and Display Port. The audio programming sequences are divided into audio
* codec and controller enable and disable sequences. The graphics driver
* handles the audio codec sequences, while the audio driver handles the audio
* controller sequences.
*
* The disable sequences must be performed before disabling the transcoder or
* port. The enable sequences may only be performed after enabling the
* transcoder and port, and after completed link training.
*
* The codec and controller sequences could be done either parallel or serial,
* but generally the ELDV/PD change in the codec sequence indicates to the audio
* driver that the controller sequence should start. Indeed, most of the
* co-operation between the graphics and audio drivers is handled via audio
* related registers. (The notable exception is the power management, not
* covered here.)
