Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

Pull drm merge from Dave Airlie:
 "Highlights:

   - TI LCD controller KMS driver

   - TI OMAP KMS driver merged from staging

   - drop gma500 stub driver

   - the fbcon locking fixes

   - the vgacon dirty like zebra fix.

   - open firmware videomode and hdmi common code helpers

   - major locking rework for kms object handling - pageflip/cursor
     won't block on polling anymore!

   - fbcon helper and prime helper cleanups

   - i915: all over the map, haswell power well enhancements, valleyview
     macro horrors cleaned up, killing lots of legacy GTT code,

   - radeon: CS ioctl unification, deprecated UMS support, gpu reset
     rework, VM fixes

   - nouveau: reworked thermal code, external dp/tmds encoder support
     (anx9805), fences sleep instead of polling,

   - exynos: all over the driver fixes."

Lovely conflict in radeon/evergreen_cs.c between commit de0babd60d8d
("drm/radeon: enforce use of radeon_get_ib_value when reading user cmd")
and the new changes that modified that evergreen_dma_cs_parse()
function.

  drm/tilcdc: only build on arm

-TODO
-. add video decode/encode support (via syslink3 + codec-engine)
-  . NOTE: with dmabuf this probably could be split into different driver
-    so perhaps this TODO doesn't belong here
-. where should we do eviction (detatch_pages())?  We aren't necessarily
-  accessing the pages via a GART, so maybe we need some other threshold
-  to put a cap on the # of pages that can be pin'd.  (It is mostly only
-  of interest in case you have a swap partition/file.. which a lot of
-  these devices do not.. but it doesn't hurt for the driver to do the
-  right thing anyways.)
-  . Use mm_shrinker to trigger unpinning pages.  Need to figure out how
-    to handle next issue first (I think?)
-  . Note TTM already has some mm_shrinker stuff..  maybe an argument to
-    move to TTM?  Or maybe something that could be factored out in common?
-. GEM/shmem backed pages can have existing mappings (kernel linear map,
-  etc..), which isn't really ideal.
-. Revisit GEM sync object infrastructure.. TTM has some framework for this
-  already.  Possibly this could be refactored out and made more common?
-  There should be some way to do this with less wheel-reinvention.
-. Solve PM sequencing on resume.  DMM/TILER must be reloaded before any
-  access is made from any component in the system.  Which means on suspend
-  CRTC's should be disabled, and on resume the LUT should be reprogrammed
-  before CRTC's are re-enabled, to prevent DSS from trying to DMA from a
-  buffer mapped in DMM/TILER before LUT is reloaded.
