This patch set is introduced to support a driver we are developing

Clients need only specify memory layout information for a single plane

Hi!
Most of CSI-1 / N900 camera support is there in linux-next tree:
patches marked "n" are in, unmarked patches are only in Sakari's tree.
Is there something I can do to help merging patches to linux-next? We
are quite close, and it would be nice to have camera support in v4.14...
