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@xxxxxxxxxx> Cc: Luis Torres <luis.torres@xxxxxxxxxxx> Cc: Scott Roberts <scott.roberts@xxxxxxxxx> Cc: Paul Arola <paul.arola@xxxxxxxxx> Cc: Andrew Lunn <andrew@xxxxxxx> Cc: Jason Cooper <jason@xxxxxxxxxxxxxx> Cc: Gregory Clement <gregory.clement@xxxxxxxxxxx> Cc: Sebastian Hesselbarth <sebastian.hesselbarth@xxxxxxxxx> Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx Signed-off-by: Vladimir Vid <vladimir.vid@xxxxxxxxxx> --- v6 changes: - updated LED labels per naming convention (Documentation/leds/leds-class.txt) --- MAINTAINERS | 5 + arch/arm64/boot/dts/marvell/Makefile | 1 + .../boot/dts/marvell/armada-3720-uDPU.dts | 164 ++++++++++++++++++ 3 files changed, 170 insertions(+) create mode 100644 arch/arm64/boot/dts/marvell/armada-3720-uDPU.dts diff --git a/MAINTAINERS b/MAINTAINERS index 51029a425dbe..21174a13049b 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -9851,6 +9851,11 @@ F: drivers/media/platform/meson/ao-cec.c F: Documentation/devicetree/bindings/media/meson-ao-cec.txt T: git git://linuxtv.org/media_tree.git +METHODE UDPU SUPPORT +M: Vladimir Vid <vladimir.vid@xxxxxxxxxx> +S: Maintained +F: arch/arm64/boot/dts/marvell/armada-3720-uDPU.dts + MICROBLAZE ARCHITECTURE M: Michal Simek <monstr@xxxxxxxxx> W: http://www.monstr.eu/fdt/ diff --git a/arch/arm64/boot/dts/marvell/Makefile b/arch/arm64/boot/dts/marvell/Makefile index 2eff1f927471..caed4334f27d 100644 --- a/arch/arm64/boot/dts/marvell/Makefile +++ b/arch/arm64/boot/dts/marvell/Makefile @@ -2,6 +2,7 @@ # Mvebu SoC Family dtb-$(CONFIG_ARCH_MVEBU) += armada-3720-db.dtb dtb-$(CONFIG_ARCH_MVEBU) += armada-3720-espressobin.dtb +dtb-$(CONFIG_ARCH_MVEBU) += armada-3720-uDPU.dtb dtb-$(CONFIG_ARCH_MVEBU) += armada-7040-db.dtb dtb-$(CONFIG_ARCH_MVEBU) += armada-8040-clearfog-gt-8k.dtb dtb-$(CONFIG_ARCH_MVEBU) += armada-8040-db.dtb diff --git a/arch/arm64/boot/dts/marvell/armada-3720-uDPU.dts b/arch/arm64/boot/dts/marvell/armada-3720-uDPU.dts new file mode 100644 index 000000000000..2441481643a4 --- /dev/null +++ b/arch/arm64/boot/dts/marvell/armada-3720-uDPU.dts @@ -0,0 +1,164 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Device tree for the uDPU board. + * Based on Marvell Armada 3720 development board (DB-88F3720-DDR3) + * Copyright (C) 2016 Marvell + * Copyright (C) 2019 Methode Electronics + * Copyright (C) 2019 Telus + * + * Vladimir Vid <vladimir.vid@xxxxxxxxxx> + */ + +/dts-v1/;
