Moikka!
Biggest issue is that CIMax2 SP2 driver. Olli put all that stuff to own I2C driver recently. Could you took SP2 from patchwork and use it instead:
https://patchwork.linuxtv.org/patch/25206/
https://patchwork.linuxtv.org/patch/25210/

It is not yet in mainline, but there should not be any big changes coming to that driver.

Antti
