[PATCH v2 0/8] media: rcar-csi2: Add support for V4M

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

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

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.
