I run on you branch on top of linux-next, but switch build options from modules to built-in

I didn't get the sensor initialized and hence there is no /dev/media0 node:

I believe the problem could be related to CCI, please remind me, are there I2C bus pull-ups?

Hmm.

Just trying to replicate this on linux-next

root@linaro-gnome:~# cam -l
Available cameras:

are you compiling everything in ?
