About pixel rate and registers, I am currently researching this topic... I honestly thought that driver would work out of the box, because you know, the name "ov2718_mipi" suggests it should work with ov2718 camera I will provide more info on this later.

Code:
[clock]
pll4 = 300
pll6 = 600
pll8 = 360
pll9 = 297
pll10 = 264
The improper clock/frequency setup might be the case.
Thanks, you gave me some ideas where to look. I'll check ov2718 manual and will be back when I get additional information.
