MAX96712 and MAX96724 have more than one GMSL2 link, and each link is capable of connecting to a separate serializer. If these serializers have the same CFG pins configuration, they will also have the same I2C address, causing conflicts unless the deserializer muxes the I2C channels. Moreover, the serializers can have the same hardware attached to their respective I2C bus. The MAX96712 and MAX96724 suppot I2C channel muxing via the GMSL2 link to facilitate communication to each of the connected serializers. Document this capability.
