This adds initial support for micro-DPU (uDPU) board which is based on Armada-3720 SoC. micro-DPU is the single-port FTTdp distribution point unit made by Methode Electronics which offers complete modularity with replaceable SFP modules both for uplink and downlink (G.hn over twisted-pair, G.hn over coax, 1G and 2.5G Ethernet over Cat-5e cable). On-board features: - 512 MiB DDR3 - 2 x 2.5G SFP via HSGMII SERDES interface to the A3720 SoC - USB 2.0 Type-C connector - 4GB eMMC - ETSI TS 101548 reverse powering via twisted pair (RJ45) or coax (F Type) Cc: Luka Perkov <luka.perkov@sartura.hr> Cc: Luis Torres <luis.torres@methode.com> Cc: Scott Roberts <scott.roberts@telus.com> Cc: Paul Arola <paul.arola@telus.com> Cc: linux-arm-kernel@lists.infradead.org Signed-off-by: Vladimir Vid <vladimir.vid@sartura.hr> Cc: Andrew Lunn <andrew@lunn.ch> --- v3 changes: - update copyright year for Methode and Telus - fix Methode copyright (use Methode Electornics instead of Methode) - sort compatible string by relevance, remove armada-3720-db and armada3710 to keep it generic --- MAINTAINERS | 5 + arch/arm64/boot/dts/marvell/Makefile | 1 + .../boot/dts/marvell/armada-3720-uDPU.dts | 163 ++++++++++++++++++ 3 files changed, 169 insertions(+) create mode 100644 arch/arm64/boot/dts/marvell/armada-3720-uDPU.dts
