Hello Matthias,

This series is about mmsys configuration of external display path.

It is in version *24*, and it is reviewed by many reviewers, like CK
and Angelo.
The reset.h is also reviewed by Krzysztof.

This series is also well tested by me and Angelo.
I tested this series with modetest successfully using 5.19-rc2 mainline
kernel with dp/dpintf/dp phy series.([1])

Could you kindly take a look for this series and give us some comments
or feedback? We really need this series being accepted.

Thanks for your big support!
