* Atomic modesetting conversion progress

* Improved validation of video modes. Some low-power chips can't
drive all DP screens and this is now detected by the driver.

* PSR and FBC improvements and bug fixes

* Workarounds for some specific HDMI monitors needing more time than
allowed by the spec to handle hot-plug events

* As usual, various fixes for little issues here and there

drm/i915: Update to Linux 4.1

* Valleyview support has been vastly improved and is no longer considered
preliminary

* Skylake support improvements: runtime power management, turbo and sleep
states should now be fully operational.
Many workarounds have been added for Skylake specific issues

* Preliminary changes to prepare for Broxton (future Atom SOCs) support

* Distinguish hardware minimum and user minimum frequencies. Set the GPU
frequency to the hardware minimum on idle in order to reduce power usage

* DRRS (dynamic refresh rate switching) is now enabled where supported.
The idea is to reduce the refresh rate of the panel to save power when
nothing changes on the screen

* DP deadlock bugfixes and improved link rate computation. Intermediate
link rate support for eDP 1.4

* XenGT client-side support. This is paravirtualization to allow virtual
machines to tap into the render engines

* Plenty of internal work to prepare for atomic mode setting

* Lots of other smaller work all over such as added documentation, dead
UMS code removal, vblank interrupt cleanings, etc...

drm/i915: Upgrade to Linux 4.0

* Basic Skylake support

* Panel Self-Refresh (PSR) now supported on Valleyview and Cherryview

* Preparations for atomic display updates

* Performance improvements on various GPU families, including Cherryview,
Broadwell and Haswell

* GPU frequencies are now kept at a minimum of 450MHz when possible
on Haswell and Broadwell, ensuring a minimum experience level for
various types of workloads

* Improved reset support for gen3/4 GPUs, which should fix some OpenGL
crashes on Core 2 and pre-2012 Atom machines

* Better sound/graphics driver synchronization for audio over hdmi support

* As usual, small bugfixes and stability improvements here and there

drm/i915: Update to Linux 3.16

* Much improved support for Broadwell GPUs. Acceleration should now be fully
operational and the giant L4 eDRAM cache is now enabled when present.

* Baytrail/Valleyview support improvements

* prelimary support for Cherryview (14nm Atom SOCs)

* Various fixes and performance improvements on most other GPU generations

* Improved runtime power management

* 5.4GHz DisplayPort support

* Large cursor support (up to 256x256 pixels), useful for high-dpi displays.

* Mapping of user pages into video memory (userptr)
This allows zero-copy downloads and efficient readback to/from the GPU,
allowing faster rendering of client-side software rasterisers, mitigation
of stalls due to read back and faster pipelining of texture data (such as
pixel buffer objects in GL or data blobs in CL). Mixed CPU/GPU operations
become more efficient in general.

drm/i915: Update to Linux 3.14

Changes specific to the DragonFly driver:

* Most GEM code paths are now similar to Linux, leading to increased
stability and performance.
Making this change was greatly helped by studying the OpenBSD code.

* We were previously using legacy functions to set up page table entries and
this was starting to become a serious problem on particular platforms such
as gen4 or Broadwell. As of this commit, we now use the same chip-specific
virtual functions as Linux.

* RC6 and Frame Buffer Compression power savings enabled by default, depending
on the GPU family

Changes brought by the Linux 3.11 => 3.14 driver update:

* Various bug fixes on all GPU generations, especially stability improvements

* Power consumption improvements

* Many Valleyview/Baytrail support improvements

* The giant 128MB L4 cache is now enabled when present on Haswell

* Added support for Broadwell GPUs

* HDMI 4K support

* basic support for 3D/stereo displays on HDMI

drm: Sync a few headers with Linux 3.8

drm/i915: Put i915_drm.h into include/

Split the header in two separate files, like it is done in Linux 3.8.

drm: Use an include directory hierarchy similar to the Linux one

drm: Replace the i915 driver by i915kms

i915kms was already an updated version of i915, there's no need to
keep maintaining two separate instances of the same driver.
