My SOC is the IMX8M Mini. I want to use its MIPI interface to capture my non-RGB CMOS image data, that is, the original data. Since this CMOS is not supported by the Linux kernel, I can only write the driver to adapt it to myself, but Because the V4L2 framework is too complicated, and my cmos frame rate is relatively high, I want to write a non-standard CMOS capture driver myself, but I checked the IMX8MM reference manual and found that there is no clear description of the MIPI acquisition. I want to confirm Is it necessary to configure the CSI Bridge to receive data using the MIPI CSI IP core? I did not find the relevant driver source of CSI Bridge in the Linux kernel source code. Only one mx6s_capture.c and his matching degree are relatively high. I used OV5640 to track the data flow of MIPI. I did not find that he used CSI Bridge. But after I commented out the csi1_bridge node of the device tree, the OV5640 will not work properly. What is going on?
