Our existing CEA modedb contains only 64 modes (VIC=1 to VIC=64). Now
to be able to parse new CEA modes using the existing methods, 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).

I'm pretty sure I've mentioned before that we need to deal with the
native bit differently for these new modes. That is, the native bit
is only present for VICs <=64. For these new VICs there is no native
bit, and if we pretend that there is we would misinterpret any
VIC >192.

Yes, I remember the discussion, just forgot it while coding :-).
I will add code to restrict native bit decoding at VIC=64

[PATCH 02/11] drm/edid: Complete CEA modedb(VIC 1-107)

2017-04-07 Thread Shashank Sharma 
CEA-861-F specs defines new video modes to be used with
HDMI 2.0 EDIDs. The VIC range has been extended from 1-64 to
1-107.

Our existing CEA modedb contains only 64 modes (VIC=1 to VIC=64). Now
to be able to parse new CEA modes using the existing methods, 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).

Cc: Ville Syrjala 
Cc: Jose Abreu 
Cc: Andrzej Hajda 
Cc: Alex Deucher 

V2: Addressed review comments from Jose:
- fix the timings for VIC 83, 90 and 91
- fix formatting for VIC 93-107

V3: Rebase on drm-tip, added R-B from Jose, Alex.
V4: Addressed review comments from Andrzej not to modify the
VIC filed for HDMI 1.4b sinks (by adding another patch).
