[PATCH 2/6] dt-bindings: net: marvell,dfx-server: Convert to yaml

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Even though this description is not used anywhere upstream (no matching
driver), while on this file I decided I would try a conversion to yaml
in order to clarify the prestera family description.

I cannot keep the nodename dfx-server@xxxx so I switched to dfx-bus@xxxx
which matches simple-bus.yaml. Otherwise I took the example context from
the only user of this compatible: armada-xp-98dx3236.dtsi, which is a
rather old and not perfect DT.

I am fine dropping this file entirely as well, if judged useless.
