In the carrier board P3449 B01 design, 114&116 are assigned to the CSI-0 2-Lane interface; 120&122 are assigned to the CSI-2. When it comes to the 4-Lane design The CSI-AB(CSI 0&1) interface is configured with CAM1_PWDN(120), CAM1_MCLK(122), while the CSI-CD(CSI4) interface is configured with CAM0_PWDN(114), CAM0_MCLK(116).
So, I am thinking of if the MCLK/PWDN configuration would be fixed once any 2/4-Lane mode is initiated or could be switched by the user.
One of my cases is we have a camera sensor module that does not have MCLK/PWDN interface or I2C interface. the sensor register configuration interface is SPI. So, how can configure it on the Jetson Nano side?
