This driver currently supports only YUYV format permutations. + * + * The driver allows manual frame rate control through s_frame_interval subdev + * operation or V4L2_CID_V/HBLANK controls, but it is known that the + * auto-exposure algorithm might modify the programmed frame rate. While the + * driver initially programs the sensor with auto-exposure and + * auto-white-balancing enabled, it is possible to disable them and more + * precisely control the frame rate. + * + * While it seems possible to instruct the auto-exposure control algorithm to + * respect a programmed frame rate when adjusting the pixel integration time, + * registers controlling this feature are not documented in the public + * available sensor manual used to develop this driver (09005aef80e90084, + * MT9V111_1.fm - Rev.
