Subject: [PATCH 0/7] phy: rockchip: usbdp: Fixes, DP 1-lane support and
 cleanups

As there are some issues with the DisplayPort support, I went
though Rockchip's BSP kernel tree and looked for fixes. I found
two small changes for the initial register setup, which do not
help with the DP issue but seem sensible in general. Afterwards
I added one more fix, which corrects an issue that effectively
results in USB-C adapters with combined USB3+DP capabilities
not being able to use the DP part.

Afterwards I added one more patch adding single-lane DP support
(found in Rockchip BSP kernel) and a couple of cleanups from my
side. These are logically independent from the fixes, but I put
all together in a single series because they need to be applied
in the right order to avoid conflicts.
