CEA-861-F specs defines new 4k video modes to be used with
HDMI 2.0 EDIDs. These modes start at VIC=93 and go all the

Our existing CEA modedb contains only 64 modes (VIC=1 to VIC=64). Now
to be able to parse 4k modes using the existing techniques, we have
to complete the modedb (VIC=65 onwards).
This patch adds:
- Timings for existing CEA video modes (from VIC=65 till VIC=92)
- Newly added 4k modes (from VIC=93 to VIC=107).

Have you addressed in some other patch my concerns regarding polluting
infoframes generated for HDMI 1.4 devices (CEA-861-E) with VICs specific
only for HDMI 2.0 (CEA-861-F) ? It will happen
for all UHD modes, see [1][2] for previous discussion.
Hello Andrzej
As you already know, the aspect ratio is indexed with the VIC, which
comes from EDID.
Now, why would a HDMI 1.4 monitor, contain a HDMI 2.0 VIC ? If it does,
its not compliant.
