Merge branch 'drm/hdmi-for-3.9' of git://anongit.freedesktop.org/tegra/linux into drm-next

Thierry writes:
"Remove a duplicate implementation of the CEA VIC lookup and move the CEA
and other mode tables to drm_edid.c to make it more difficult to create
duplicates of the tables.

Add some helpers to pack CEA-861/HDMI AVI, audio and SPD infoframes into
binary buffers that can easily be written into hardware registers. A new
helper function makes it easy construct an AVI infoframe from a DRM
display mode.

Convert the Tegra and Radeon drivers to use the new HDMI helpers."
* 'drm/hdmi-for-3.9' of git://anongit.freedesktop.org/tegra/linux:
  drm/radeon: Use generic HDMI infoframe helpers
  drm/tegra: Use generic HDMI infoframe helpers
  drm: Add EDID helper documentation
  drm: Add HDMI infoframe helpers
  video: Add generic HDMI infoframe helpers
  drm: Add some missing forward declarations
  drm: Move mode tables to drm_edid.c
  drm: Remove duplicate drm_mode_cea_vic()
