Subject: [media] uvcvideo: Support 10bit, 12bit and alternate 8bit greyscale formats Author: Stefan Muenzel <[email protected]> Date: Sat Jul 28 19:49:14 2012 -0300 The SPCAM SP620U camera uses the alternate "Y8 " GUID for the 8-bit greyscale format, and supports a 12-bit greyscale format. Add support for those in the driver, as well as for 10-bit greyscale formats.
