Hello,
I have been looking around for a means to directly interface MIPI CSI-2 Sensors (Mobile Cameras mainly) with Linux-Based ARM devices, and found papers from several researchers who have succeeded or at made gains toward using these devices. These types of cameras are used by ARM devices like the Raspberry Pi (with the PiCam).

There really aren't any/many drivers out there to run these devices on Linux (that I know of), so hopefully this post can help.
Thanks
