Brian,

Thank you for the information. Sorry I didn't know that there is
already a patch. I'm working on the resolution problem now ( Change
SN9c202 to 1280x1024 ). But no luck so far.


int mt9m111_set_autoexposure(struct usb_sn9c20x *dev)
{
        __u16 buf[1];
        int page = 0;
        int ret = 0;
        int data = 0x3080;

        switch (dev->vsettings.auto_exposure) {
        case V4L2_EXPOSURE_AUTO:
                data|=0x7000;
                data|=0x000C;
        break;
        case V4L2_EXPOSURE_MANUAL:
                data&=~0x7000;
        break;
        case V4L2_EXPOSURE_SHUTTER_PRIORITY:
                data|=0x7000;
                data&=~0x000C;
        break;
        case V4L2_EXPOSURE_APERTURE_PRIORITY:
                data|=0x7000;
                data&=~0x000C;
                data|=0x0004;
        break;
        default:
                return -EINVAL;

You don't have to use such a big switch. Another one of Brian's patches reduces the option for auto_exposure to 1 (auto) and 0 (manual). This is not exactly V4L2 compliant but it is more intuitive in our case.

Why have none of these changes found their way into the repo? Ican't even find the commit which fixes the byte-order for bayer. If the first mail contains all that I can make a patch but there were some objections if I remember correctly.
