This small series is very much work in progress, but I still wanted to get feedback in this early stage to gather requirements from the folks working on the display drivers that these helpers target. Patch 1 in the series adds a generic helper to pack a structure that describes an HDMI AVI infoframe into the binary format as specified in the HDMI specification. The resulting binary buffer should be easily programmable into the HDMI controller. Patch 2 provides a helper to fill an HDMI AVI infoframe with data from a struct drm_display_mode. This is all pretty rough right now, but I think some feedback would be good at this point, to see if the design is at all sensible. I should also mention that I haven't actually tested this on real hardware yet. Furthermore I have plans to add something similar for the other types of infoframes specified by HDMI once the direction becomes clearer.
