Subject: [PATCH V2 1/4] media: dt-bindings: ti,ds90ub960: Refactor port definitions
The current bindings duplicate the port definitions for each FPD-Link RX
and CSI-2 TX ports. This results in a large amount of repeated schema
blocks and makes it harder to extend the bindings for new devices.
Refactor the bindings by introducing shared deftinitions for FPD-Link
input ports and CSI-2 output ports. No functional change intended.
