 10 *
 11 * The board .dts file that include this has to select which cameras are in use
 12 * by specifying the camera model with:

 14 * #define GMSL_CAMERA_RDACM20
 15 * or
 16 * #define GMSL_CAMERA_RDACM21
 17 *
 18 * And which cameras are connected to the board by defining:
 19 * for GMSL channel 0:
 20 *	   #define GMSL_CAMERA_0
 21 *	   #define GMSL_CAMERA_1
 22 *	   #define GMSL_CAMERA_2
 23 *	   #define GMSL_CAMERA_3
 24 *
 25 * for GMSL channel 1:

 27 *	   #define GMSL_CAMERA_5
 28 *	   #define GMSL_CAMERA_6
