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
way till VIC=107.

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).
As I understand it modifies edid_cea_modes array. This array
is used by couple of functions, particularly by drm_match_cea_mode,
which is used by drm_hdmi_avi_infoframe_from_display_mode.
I.e. since this patch AVI infoframes generated using drm core code will
be different - they can contain VIC codes unknown to TV.
I am not sure if it is harmful, but for sure this patch has visible
impact on drivers behavior.

Maybe it would be good to allow drivers to keep full compatibility with
HDMI 1.4?
Hello Andrzej,
Thanks for the comment.
If you watch the code flow carefully, this is driven by EDID. So any
VIC, which is translated/transformed using this array, would be coming
from the EDID itself.
No. The user is free to specify any mode they wish. It doesn't have to
come from the EDID. Not sure specifying a modern VIC for an older
display is a good idea or not. If not, we could always check the cea_rev
assuming it changed whenever the list if VICs was expanded.
I agree, that user can specify a mode, out of EDID too.
I am anyways planning to add a patch, where before loading HDMI 2.0 VICs
in AVI IF, we are checking the EDID rev.
That should solve our problem.

So if edid_rev < 2.0
      do_not_load VICs from 93 - 107, but keep it 0.
Why edid_rev and not cea_rev?
We can do that also, but in the current structure, we are already caching EDID rev, its just about re-using it.
AFAIK, we don't have CEA extension cached anywhere.

So I dont think there would be a problem if the mode is defined in the
EDID section itself, coz we are expecting the TV to know what its
mentioning in EDID.

This is how a typical flow would look:
- hot-plug
- driver reads modes specified in EDID basic.
- driver parses various CEA extension blocks.
       - For both of the above mentioned steps, driver will probe the
functions like do_cea_modes which uses edid_cea_modes[] array.
- driver will add the probed modes in EDID, into connector
- driver will pass the connector to userspace
- userspace will pick one of the probed modes for modeset.
- during modeset, we will set VIC part for a CEA mode, in the AVI
infoframe section.

So in other words, the only source of a VIC (cea_mode) is from TV's own
EDID.
This means we should never run into an unknown VIC. There can be a 0 VIC
(for non CEA modes), but not unknown one.
