Merge branch 'for-airlied' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

Daniel writes:
Highlights of this -next round:
- ivb fdi B/C fixes
- hsw sprite/plane offset fixes from Damien
- unified dp/hdmi encoder for hsw, finally external dp support on hsw
  (Paulo)
- kill-agp and some other prep work in the gtt code from Ben
- some fb handling fixes from Ville
- massive pile of patches to align hsw VGA with the spec and make it
  actually work (Paulo)
- pile of workarounds from Jesse, mostly for vlv, but also some other
  related platforms
- start of a dev_priv reorg, that thing grew out of bounds and chaotic
- small bits&pieces all over the place, down to better error handling for
  load-detect on gen2 (Chris, Jani, Mika, Zhenyu, ...)

On top of the previous pile (just copypasta):
- tons of hsw dp prep patches form Paulo
- round scheduled work items and timers to nearest second (Chris)
- some hw workarounds (Jesse&Damien)
- vlv dp support and related fixups (Vijay et al.)
- basic haswell dp support, not yet wired up for external ports (Paulo)
- edp support (Paulo)
- tons of refactorings to prepare for the above (Paulo)
- panel rework, unifiying code between lvds and edp panels (Jani)
- panel fitter scaling modes (Jani + Yuly Novikov)
- panel power improvements, should now work without the BIOS setting it up
- extracting some dp helpers from radeon/i915 and move them to
  drm_dp_helper.c
- randome pile of workarounds (Damien, Ben, ...)
- some cleanups for the register restore code for suspend/resume
- secure batchbuffer support, should enable tear-free blits on gen6+
  Chris)
- random smaller fixlets and cleanups.
