Patch 1 adds the binding for the new device. This patch was posted separately in v1 but have now been folded in to this series. Patch 2-3 clean up some simplifications in the driver which where possible before V4M support but that now needs to be addressed. Patch 4-6 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 7 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 8 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. See individual patches for changelog.
