--- Comment #21 from Sonika <sonika.jindal at intel.com> ---
I tried on another SKL system, which has panel whose DPCD is same as your
panels with HBR2 enabled:
[drm:intel_dp_get_dpcd] DPCD: 12 14 c4 41 00 00 01 c0 02 00 00 00 1f 0b 00

System + bios details:
Intel Corporation Skylake Client platform/Skylake U DDR3L RVP7
BIOS SKLSE2R1.86C.B067.R00.1412310711 12/31/2014

It still works for me with default table as well as edp translation table.
Please note that, I try by hardcoding this value in code to make use of the low
vswing table.
