Merge branch 'exynos-drm-next' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-next

Feature summary:
Add S3C64XX SoC series support - S3C64XX SoC series are previous version
chips of Exynos SoC series. With this patch set, KMS driver of Exynos drm
supports those chips also.

Update device tree support - This patch set corrects compatible strings,
and adds Exynos5420 SoC support for hdmi subsystem.

Consider CCF (Common Clock Framework) support - With reference to CCF
support, it uses clock_prepare_enable/clock_disable_unprepare instead of
clk_enable/clk_disable for hdmi subsystem.

Big cleanups - This patch just removes unnecessary all debug logs.

reservation: cross-device reservation support, v4

This adds support for a generic reservations framework that can be
hooked up to ttm and dma-buf and allows easy sharing of reservations
across devices.

The idea is that a dma-buf and ttm object both will get a pointer
to a struct reservation_object, which has to be reserved before
anything is done with the contents of the dma-buf.

Changes since v1:
 - Fix locking issue in ticket_reserve, which could cause mutex_unlock
   to be called too many times.
Changes since v2:
 - All fence related calls and members have been taken out for now,
   what's left is the bare minimum to be useful for ttm locking conversion.
Changes since v3:
 - Removed helper functions too. The documentation has an example
   implementation for locking. With the move to ww_mutex there is no
   need to have much logic any more.

Merge tag 'drm-intel-next-2013-06-18' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

Last 3.11 feature pull. I have a few odds bits and pieces and fixes in my
queue, I'll sort them out later on to see what's for 3.11-fixes and what's
for 3.12. But nothing to hold this here up imo.

Highlights:
- more hangcheck work from Mika and Chris to prepare for arb robustness
- trickle feed fixes from Ville
- first parts of the shared pch pll rework, with some basic hw state
  readout and cross-checking (this shuts up the confused pch pll refcount
  WARN that Linus just recently forwarded)
- Haswell audio power well support from Wang Xingchao (alsa bits acked by
  Takashi)
- some cleanups and asserts sprinkling around the plane/gamma enabling
  sequence from Ville
- more gtt refactoring from Ben
- clear up the adjusted->mode vs. pixel clock vs. port clock confusion
- 30bpp support, this time for real hopefully
