Hi,

This patch series contain backports of several fixes/improvements taken from the
donwstream Raspberry Pi kernel tree:

Patch 1/5 improves the handling of frame sequence numbering.
Patch 2/5 allows userland clients to return CSI-2 unpacked formats from Unicam.
Patch 3/5 fixes an intermitent HW bug where the first frame shows corruption.
Patch 4/5 fixes a possibly HW overflow when using the dummy buffer.
Patch 5/5 improves the robustness of the interrupt handling, particulary during
fast framerate operation.

All these patches have been present in the downstream RPi tree for some time now
and have been validated by our users.

Thanks,
Naush
