The GMSL link carries power, control (I2C) and video data over a single coax cable. The driver is split between the camera module driver (rdacm20.c) and the serializer library driver (max9271.c) as the same serializer is used in multiple camera modules. The usage of a library maximises code reuse and reduces duplications.
