    Subject[PATCH 2/2] arm64: dts: marvell: add support for Methode eDPU
    Date
    Methode eDPU is an Armada 3720 powered board based on the Methode uDPU.

    They feature the same CPU, RAM, and storage as well as the form factor.

    However, eDPU only has one SFP slot plus a copper G.hn port.

    In order to reduce duplication, split the uDPU DTS into a common one.
