Merge tag 'topic/drm-misc-2015-09-25' of git://anongit.freedesktop.org/drm-intel into drm-next

Another attempt at drm-misc for 4.4 ...
- better atomic helpers for runtime pm drivers
- atomic fbdev
- dp aux i2c STATUS_UPDATE handling (for short i2c replies from the sink)
- bunch of constify patches
- inital kerneldoc for vga switcheroo
- some vblank code cleanups from Ville and Thierry
- various polish all over

* tag 'topic/drm-misc-2015-09-25' of git://anongit.freedesktop.org/drm-intel: (57 commits)
  drm/irq: Add drm_crtc_vblank_count_and_time()
  drm/irq: Rename drm_crtc -> crtc
  drm: drm_atomic_crtc_get_property should be static
  drm/gma500: Remove DP_LINK_STATUS_SIZE redefinition
  vga_switcheroo: Set active attribute to false for audio clients
  drm/core: Preserve the fb id on close.
  drm/core: Preserve the framebuffer after removing it.
  drm: Use vblank timestamps to guesstimate how many vblanks were missed
  drm: store_vblank() is never called with NULL timestamp
  drm: Clean up drm_calc_vbltimestamp_from_scanoutpos() vbl_status
  drm: Limit the number of .get_vblank_counter() retries
  drm: Pass flags to drm_update_vblank_count()
  drm/i915: Fix vblank count variable types
  drm: Kill pixeldur_ns
  drm: Stop using linedur_ns and pixeldur_ns for vblank timestamps
  drm: Move timestamping constants into drm_vblank_crtc
  drm/fbdev: Update legacy plane->fb refcounting for atomic restore
  drm: fix kernel-doc warnings in drm_crtc.h
  vga_switcheroo: Sort headers alphabetically
  drm: Spell vga_switcheroo consistently
