Depends which version of the camera userspace code you've got.  The
stuff for cupcake/donut talks directly to the DSP and the DSP
interacts with the VFE (video frontend, the camera data transport).  I
believe the new camera driver bypasses some (all?) of that and deals
with the VFE directly.  At least on 8k that's how it works (no DSP
involvement at all).
