Comment= # 2 on bug 98352<= /a> from Ville Syrjala 
The problem on this machine seems to be that the clock is abou=
t .6% off,
whereas the test will accept a deviation up to .5%.

I also have a VLV machine with DSI that suffers from a similar problem. I t=
hink
for internal panels the best solution might be for the kernel to fix up the
reported clock for the fixed mode. Not sure what we'd do about the EDID tho=
ugh,
assuming the the panel has one and the difference in the clocks would be la=
rge
enough to be visible in the EDID timings. And of course not all modes coming
from the EDID even have actual detailed timing descriptors.
