HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64). For any other mode, the VIC filed in AVI infoframes should be 0. HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function drm_hdmi_avi_infoframe_from_display_mode but to make sure there is no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch: - checks if the connected display is HDMI 2.0. - HDMI infoframes carry one of this two type of information: - VIC for 4K modes for HDMI 1.4 sinks - S3D information for S3D modes As CEA-861-F has already defined VICs for 4K videomodes, this patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks, until the mode is 3D.

PS: This patch touches a few lines in few files, which were already above 80 char, so checkpatch gives 80 char warning again. - gpu/drm/omapdrm/omap_encoder.c - gpu/drm/i915/intel_sdvo.c
V2: Rebase, Added r-b from Andrzej V3: Addressed review comment from Ville: - Do not send VICs in both AVI-IF and HDMI-IF send only one of it. V4: Rebase V5: Added r-b from Neil. Addressed review comments from Ville - Do not block HDMI vendor IF, instead check for VIC while handling AVI infoframes
