You can drop all the endpoint stuff. Just 'endpoint' should be valid as
well for example. The graph schema covers all that.

Isn't this the port dedicated to the CSI-2 receiver input ?

And the andpoint should describe the connection between the CRU and
the CSI-2 receiver ? (ie it should not contain CSI-2 specific
properties, as those are specified by the CSI-2 receiver device node?)

+description:
+ The RZ/G2L Camera Data Receiving Unit (CRU) device provides video input
+ capabilities for the Renesas RZ/G2L family of devices.
+
+ Depending on the instance the Image Processing input is connected to
+ external SoC pins or to a CSI-2 receiver.
