[00/17] media: atomisp: Convert to videobuf2

Hi All,

This patch series converts the staging atomisp driver to use the videobuf2
framework, fixing MMP mode now working.

This also contains an important fix to try_fmt handling, so that
the various supported output formats can actually be used by userspace
which calls try_fmt before doing s_fmt.

One thing missing from this conversion is moving over to using a per queue
mutex. After getting the basic videobuf2 conversion in place I first needed
to do a bunch of other fixes (like the try_fmt one) to make camorama work
again, so I ran out of time this weekend.

There is a bunch of preparation in the form of commented
out code + FIXME comments in "media: atomisp: Convert to videobuf2"
this causes a bunch of checkpatch warnings. Moving to a per queue
mutex is my next planned patch (series?).

So slowly this is starting to look more and more like a standard
v4l2 device (with all the complex pipeline handling hidden in the driver,
moving that to userspace seems to be impossible with this design since
multiple pipeline steps are handled by a single firmware program).

Regards,

Hans
