--- Comment #59 from Manasi <manasi.d.navare at intel.com> ---
Here's an update on this bug:

Found that this specific panel requires a higher panel power cycle delay no
less than 800msecs which is 300ms greater than the eDP min value. With this
value it is able to power cycle the edp panel correctly and can turn it back on
correctly without any aux ch timeouts. 

I tried this fix on Trybot multiple times and consistently got all Success on
6700hq system:
https://patchwork.freedesktop.org/series/26172/

I am working on a patch that would add it in the quirk database for this panel.

JaniN, Ville let me know what you think about this quirk?
