[PATCH 01/21] media: dt-bindings: ite,it6625: document the default CSI-2 bus type

[Hermes Wu via B4 Relay]

From: Hermes Wu <Hermes.wu@xxxxxxxxxx>

bus-type is optional under port@0 and port@1's endpoint for ite,it6625
(the allOf/if/then clause only requires it for ite,it6626, which
supports both C-PHY and D-PHY and needs disambiguation). With bus-type
omitted, the actual runtime default is D-PHY:
v4l2_fwnode_endpoint_parse_csi2_bus() falls back to
V4L2_MBUS_CSI2_DPHY whenever data-lanes is present, which this binding
already requires. Document that default explicitly instead of leaving
it unstated.
