* Device Tree Source (overlay) that describes GMSL camera connected to

*
* The following cameras are currently supported: RDACM20 and RDACM21.
*
* The board .dts file that include this has to select which cameras are in use
* by specifying the camera model with:
*
* #define GMSL_CAMERA_RDACM20
* or
* #define GMSL_CAMERA_RDACM21
*
* And which cameras are connected to the board by defining:
* for GMSL channel 0:
* #define GMSL_CAMERA_0
* #define GMSL_CAMERA_1
* #define GMSL_CAMERA_2
* #define GMSL_CAMERA_3
*
* for GMSL channel 1:
* #define GMSL_CAMERA_4
* #define GMSL_CAMERA_5
* #define GMSL_CAMERA_6
* #define GMSL_CAMERA_7
