BGR555 for example, the bridge (pxa_camera) will "forward" to RAM the image in the very same cc (ie. BGR555). In that case, the bridge is a dummy "sensor to RAM" bus translator if you prefer. Marek, you should activate debug trace and watch for yourself. You can trust Guennadi, when he says it will work, well ... it will work. If it's out of technical curiousity, check the function above. If you're even more curious, there was a thread in linux-media about "RFC: bus configuration setup for sub-devices", a very interesting one, especially considering the "pass-through" issue.
