N900 contains front and back camera, with a switch between the
two. This adds support for the switch component, and it is now
possible to select between front and back cameras during runtime.

IIRC for controlling cameras on N900 there are two GPIOs. Should
not you have both in switch driver?

I guess you recall wrongly :-). Switch seems to work. The issue was
with switch GPIO also serving as reset GPIO for one sensor, or
something like that, if _I_ recall correctly ;-).

I have a schematic in my master thesis, which shows how the camera
sensors are connected to the SoC. The PDF is available here:

The schematic is on page 37 (or 45 if your PDF reader does not
use different numbers for the preamble stuff).
