Hello,

This series enables support for R-Car V4M to the CSI-2 receiver.

Patch 1-2 clean up some simplifications in the driver which where 
possible before V4M support but that now needs to be addressed.

Patch 3-5 prepares for V4M support by extending some of the abstractions 
used in the driver to cover how they are implemented in the V4M version 
of the CSI-2 IP.

Patch 6 improves the documentation around two registers used on Gen4 as 
later datasheets now document them and they will be used when enabling 
V4M support.

And finally patch 7 adds V4M support. The V4M is similar in design to 
V4H with the big difference it only supports CSI-2 D-PHY. All of the 
media graph setup and V4L2 callbacks can be reused, only the start 
procedure is different.
