If you are referring to OMAP3 interface here then 8->16 bit conversion happens inside ISP-bridge, the interface from sensor-to-CCDC is still 8 bit (Technically it is 10, but we are using lane shifter to get 8 bits) and I believe sensor is also sending one component for every cycle (either UYVY or YUYV). And I believe the bridge driver is not exported to user application so we should be using MBUS_FMT_UYVY8_2x8 and family.
