The Samsung CSIS MIPI receiver provides a start-of-frame interrupt and a framecount register. As the CSI receiver is the hardware unit that lies closest to the sensor, the frame counter is the best we can get on these devices. In case of the ISI available on the i.MX8 M Plus it is also the only native start-of-frame signal available. This patch exposes the sof interrupt and the framecount as V4L2_EVENT_FRAME_SYNC event on the subdevice. It was tested on a Debix-Som-A with a 6.8-rc4 kernel. Reviewed-by:

The atomisp driver's Android heritage makes it weird in that even though it uses MC + subdev-s it is designed to primarily be controlled through its /dev/video# node. It implements s_input() on /dev/video# to select which sensor to use, while ignoring link_setup() calls to enable a link to another sensor. Add support for selecting the active sensor the MC way by adding link_setup() support. The implementation is a bit convoluted due to the atomisp driver's heritage. Reviewed-by:

The allocation failure of mycs->yuv_scaler_binary in load_video_binaries() is followed with a dereference of mycs->yuv_scaler_binary after the following call chain: sh_css_pipe_load_binaries() |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) | |-> sh_css_pipe_unload_binaries() |-> unload_video_binaries() In unload_video_binaries(), it calls to ia_css_binary_unload with argument &pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer dereference is triggered.
