6.6-stable review patch. If anyone has any objections, please let me know.

From: Konrad Dybcio konrad.dybcio@linaro.org
[ Upstream commit c20b59b2996c89c4f072c3312e6210528a298330 ]
The EUSB2 repeater requires some alterations to its init sequence, depending on board design.
Add support for making the necessary changes to that sequence to make USB functional on SM8550-based Xperia 1 V.
They all have lackluster description due to lack of information.
