--- Comment #43 from Manasi <manasi.d.navare at intel.com> ---
Ricardo, does the patch with 5 retries of link training (clock recovery plus
channel EQ) still work for you to fix this issue?
In that case, the patch will have to be modified to add a quirk for this
specific dongle OUI to add this retry loop outside of the DP spec only in case
of this dongle.

This dongle seems to not follow the DP spec and needs more retries for clock
recovery.
