6802d4bad8 drm/radeon/DCE4+: clear bios scratch dpms bit (v2)
The BlankCrtc table in some DCE8 boards has some
logic shortcuts for the vbios when this bit is set.
Clear it for driver use.

v2: fix typo

f5395ba35f Merge branch 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux into drm-next
Here's the vblank timestamp pull request you wanted.

I addressed the few bugs that Mario pointed out and added
the r-bs.

As it has been a while since I made the changes, I gave it a
quick spin on a few different i915 machines. Fortunately
everything still seems to be fine.

* 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux:
  drm/i915: Add a kludge for DSL incrementing too late and ISR not working
  drm/radeon: Move the early vblank IRQ fixup to radeon_get_crtc_scanoutpos()
  drm: Pass 'flags' from the caller to .get_scanout_position()
  drm: Fix vblank timestamping constants for interlaced modes
  drm/i915: Fix scanoutpos calculations for interlaced modes
  drm: Change {pixel,line,frame}dur_ns from s64 to int
  drm: Use crtc_clock in drm_calc_timestamping_constants()
  drm/radeon: Populate crtc_clock in radeon_atom_get_tv_timings()
  drm: Simplify the math in drm_calc_timestamping_constants()
  drm: Improve drm_calc_timestamping_constants() documentation
  drm/i915: Call drm_calc_timestamping_constants() earlier
  drm/i915: Kill hwmode save/restore
  drm: Pass the display mode to drm_calc_vbltimestamp_from_scanoutpos()
  drm: Pass the display mode to drm_calc_timestamping_constants()

265d09aa82 drm/radeon: Populate crtc_clock in radeon_atom_get_tv_timings()
crtc_clock is now supposed to be the actual pixel clock corresponding to
the other crtc_ timing values. Populate crtc_clock appropriately in
radeon_atom_get_tv_timings().

This was the only obvious place where we frob with the crtc_ timigns
directly instead of calling drm_mode_set_crtcinfo() which would also
update crtc_clock.

fb93df1c2d drm/radeon: fix handling of variable sized arrays for router objects
The table has the following format:

typedef struct _ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT         //usSrcDstTableOffset pointing to this structure
{
  UCHAR               ucNumberOfSrc;
  USHORT              usSrcObjectID[1];
  UCHAR               ucNumberOfDst;
  USHORT              usDstObjectID[1];
}ATOM_SRC_DST_TABLE_FOR_ONE_OBJECT;

usSrcObjectID[] and usDstObjectID[] are variably sized, so we
can't access them directly.  Use pointers and update the offset
appropriately when accessing the Dst members.

612a9aab56 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.
