I found it from the archive at http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/32700/focus=32721 I read through the threads and see that I'm indeed in similar situation with Alex. We both have sensor that output CMOS H/V image and only have UART/RS232 for control of the sensor operations via sending/reading packet of bytes. i.e. AGC, contrast, brightness etc.. Since the thread ended on 29-Jun, is there anymore update or information? As I've a MT9V032 camera with Gusmtix Overo, I was hoping to rely on the MT9V032 driver as a starting point and adapt it for the VL5510 sensor using only the UART interface.
