4 weeks worth of stuff since I was traveling&lazy:

- lspcon improvements (Imre)
- proper atomic state for cdclk handling (Ville)
- gpu reset improvements (Chris)
- lots and lots of polish around fences, requests, waiting and
  everything related all over (both gem and modeset code), from Chris
- atomic by default on gen5+ minus byt/bsw (Maarten did the patch to
  flip the default, really this is a massive joint team effort)
- moar power domains, now 64bit (Ander)
- big pile of in-kernel unit tests for various gem subsystems (Chris),
  including simple mock objects for i915 device and and the ggtt
  manager.
- i915_gpu_info in debugfs, for taking a snapshot of the current gpu
  state. Same thing as i915_error_state, but useful if the kernel didn't
  notice something is stick. From Chris.
- bxt dsi fixes (Umar Shankar)
- bxt w/a updates (Jani)
- no more struct_mutex for gem object unreference (Chris)
- some execlist refactoring (Tvrtko)
- color manager support for glk (Ander)
- improve the power-well sync code to better take over from the
  firmware (Imre)
- gem tracepoint polish (Tvrtko)
- lots of glk fixes all around (Ander)
- ctx switch improvements (Chris)
- glk dsi support&fixes (Deepak M)
- dsi fixes for vlv and clanups, lots of them (Hans de Goede)
- switch to i915.ko types in lots of our internal modeset code (Ander)
- byt/bsw atomic wm update code, yay (Ville)
