Wed Aug 8 14:53:05 UTC 2018
From: Mikita Lipski <mikita.lipski at amd.com>
[why]
HDMI and DVI share the same PHY clock and single link
DVI and HDMI both use 4 lanes, so they should be allowed
to be sharing the same clock source if all other parameters
are satisfied.
[how]
Change a check for general DVI to Dual DVI.
