When using the sonixb driver in a dark room and given that the autoexposure algorithm starts with a setting most suitable for daylight, the picture produced by the cam may actually be 100% black leading to a avg_lum value of 0, so an avg_lum value of 0 does not always signal an exposure settings change (which it normally does). This patch adds a check for the really black image case and stops dropping all frames as invalid in this case. Signed-off-by:

This patch makes gspca claim the USB-ID for sn9c101/2 cams with a TAS5110C1B sensor even if both gspca and sn9c102 are enabled, as these cams are much better supported under gspca (and extensively tested with gspca). It also removes an usb-id from sn9c102 for one more unsupported bridge sensor combo. Signed-off-by:

- Add documentation for some known registers - Add support for vga modes (320x240, 160x120) for sif sensors - Remove F_RAW sensor flag raw mode should work on any sensor as its a bridge only thing and keeping the flag was becoming awkward. - Fixup ov6650 and pas106 auto exposure window settings Signed-off-by:

This adds basic support for the Hauppauge Nova-TD-500 84xxx series. A future patch will allow for one aerial input to supply both tuners. With the current code, an aerial must be plugged into each antannae input in order for both tuners to function. Signed-off-by:

Some DVB drivers are incorrectly assuming that the size of i2c_adapter.name is I2C_NAME_SIZE. Here's a fix. Also change strncpy to strlcpy, as the former is error-prone (and was indeed incorrectly used.) Signed-off-by:

1) Lower the hstart setting for all sensor by 1 so that we generate (compressed) BGGR data just like sn9c102 does (instead of GBRG data) 2) Add support for raw bayer output in the lowest resolutions (not enough bandwidth for higher resolutions), this should work with all sensors but to be sure only enable it for sensors where it has been tested.

Under certain conditions sonixb compressed frame size can get bigger then the uncompressed size (seen with 0c45:6028), so make the buffers slightly bigger. Signed-off-by:

-the usb-id table caried several flags which were not usb-id specific but sensor specific, add a sensor_data array and move these flag there -fr_h_sz was being abused to store and check which bridge was being used instead add a bridge member to the sd struct -now that we have a sensor_data table use that to store pointers to init_sequences instead of using switch cases on sd->sensor Signed-off-by:
