Yes I will add the bus-type propery

+description: |
+ The MAX96717F serializer converts MIPI CSI-2 D-PHY or C-PHY formatted input
+ into GMSL2 serial outputs. The device allows the GMSL2 link to
+ simultaneously transmit bidirectional control-channel data while forward
+ video transmissions are in progress. The MAX96717F can connect to one
+ remotely located deserializer using industry-standard coax or STP
+ interconnects. The device cans operate in pixel or tunnel mode. In pixel mode
+ the MAX96717F can select the MIPI datatype, while the tunnel mode forward all the MIPI
+ data received by the serializer.
+ The MAX96717F supports Reference Over Reverse (channel),
+ to generate a clock output for the sensor from the GMSL reverse channel.
+
+ The GMSL2 serial link operates at a fixed rate of 3Gbps in the
+ forward direction and 187.5Mbps in the reverse direction.
