Contrast and brightness should work on all the cameras since they are controlled by the bridge which is the same for all cameras. Gain is only implemented for the Omnivision based sensors and your camera has a micron sensor so no that won't work. You can find out what sensor you have by typing dmesg right after you insert the driver module. There should be a line thats says something like "sn9c20x: Detected <name> Sensor"
You probably have a mt9v111 but your camera could be any one of three different sensors. In regards to auto-exposure you could try siwthving your sensor to have the driver calculate the exposure settings based on the bridges AE window instead of letting the sensor do it and see if those results are any better. Do try that you need to edit sn9c20x-dev.c file and in the sn9c20x_initialize_sensor function find your sensor and remove the line that sets the autpexposure callback.
