I got OT. I just needed to vent!

Sorry for the spam.

For the sensor mounting, I think the cam knows how the sensor is mounted 
and therefor the driver knows (driver -> first abstraction layer between 
software and hardware). Therefor the drive has to report the sensor 
orientation to user space (read only).

PS: May be, I am OT all ready.
