I add support for OV7742 (plugged on CSI port) on kernel 3.10.17. This camera is able to support banding filter and a few other useful features. These features are correctly supported by V4L API (see V4L2_CID_POWER_LINE_FREQUENCY, V4L2_CID_BAND_STOP_FILTER, ... ). However, mxc_v4l2_capture only forward a few subset of V4L controls to camera driver (see mxc_v4l2_s_ctrl() in mxc_v4l2_capture.c). Should I patch mxc_v4l2_capture.c in order to support them, or I have missed something?
