I have just used this driver to interface to a soc imager (Aptina
mt9p031) on the phyCORE-i.MX27 board. It works for acquiring a 640x480
video stream quite reliably. I am currently working on getting it to
be able to capture a full image frame (5MB) as well as various image
sizes in between. I am running into out of memory issues with the
dma_alloc_coherent() and not sure what the solution is yet.
