To get direct access to userspace memory pages vb2 allocator needs to
gather read access on mmap semaphore in the current process.
The same semaphore is taken before calling mmap operation, while
both mmap and qbuf are called by the driver or v4l2 core with
driver's lock held. To avoid a AB-BA

DM365. A few more implementation patches which include Resizer, Previewer ,
AEW and AF are added to provide a broader perspective for review.

davinci: vpfe: add dm3xx IPIPEIF hardware support
Add auto exposure and white balance driver based on v4l2 media
framework. The driver processess the bayer data from CCDC and
generates the data which will be used for calculation of
parameters responsible for auto exposure and white balancing.
The driver implement the v4l2 event queing mechanism
Add autofocus driver based on v4l2 media framework. The driver
processess the bayer data from CCDC and generates the data which
will be used for calculation of parametsrs responsible for focussing.
The driver implement the v4l2 event queing mechanism to know the
readiness data from the driver.

lowest software layer for the dm3x vpfe driver which directly
accesses hardware. Add support for features like default
pixel correction, dark frame substraction and hardware setup.
