Actually it doesn't. The DT bindings specifies "default-input" as an endpoint
property, even though the example sets it in the device node. That's
inconsistent so the DT bindings document should be fixed. I believe the
property should be set in the device node, it doesn't make much sense to have
different default inputs per port.
