The first two patches are of a janitorial nature, the first converting the drm_num_cea_modes constant to unsigned and the second adding a few missing forward declarations in order to fix build issues.
Patch 3 adds generic helpers to pack a structures that describe HDMI AVI, audio, vendor-specific or SPD infoframes into the binary format specified in the HDMI specification. The resulting binary buffer should be easily programmable into the HDMI controller.
Patch 4 provides a helper to fill an HDMI AVI infoframe with data from a struct drm_display_mode.
Patch 5 adds the DRM EDID helpers (including the new DRM HDMI helper from patch 4) to the DRM DocBook documentation.
Patch 6, 7 and 8 move the Tegra, Intel and Radeon drivers over to the new helpers. Patch 7 was contributed by Intel's Paulo Zanoni.
Finally, patch 9 removes the drm_mode_cea_vic() function which is a duplicate implementation of the older drm_match_cea_mode().
I haven't gotten around to converting the Exynos driver reimplementation because it isn't as trivial as the others. Nouveau also has some code to write infoframes and I'll see if I can convert those next.
One item that I have on my TODO list is the ACR computations requested by Christian König. My schedule has been really busy lately, so I'm not sure how long it will take until I get to it. I'd appreciate it if we could merge this series without the ACR implementation in order to get at least the numerous infoframe reimplementations cleaned up and to prevent others from getting in.
