[Bug 89554] [SKL Bisected] eDP can not be lighted up after entering kernel

--- Comment #2 from Sonika <sonika.jindal at intel.com> ---
For me with kernel version 4.0.0-rc3, eDP is working fine.

The EDP low vswing table gets selected only when edp_vswing_preemph is set in
vbt.
For me, it works with both low vswing table as well as the dp translation table
with an edp1.3 panel.

Only thing I can suspect is that we are trying to use low vswing table for some
panel which is not able to handle those values.
Can you please see if this variable is set in vbt?
If it is set, please try to disable it and try.
