From c0def248caa5e2e6ed63249d3713830bd27e31e6 Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Thu, 22 Sep 2016 12:56:14 +1200 Subject: arm: mvebu: add DB-88F6820-AMC board This board is a plug in card for Marvell's switch system development kits. Form-factor aside it is similar to the DB-88F6820-GP with the following differences. - TCLK is 200MHz - SPI1 is used - No SATA - No MMC - NAND flash Reviewed-by: Simon Glass Signed-off-by: Chris Packham Signed-off-by: Stefan Roese --- arch/arm/dts/Makefile | 1 + arch/arm/dts/armada-385-amc.dts | 155 ++++++++++++++++++++++++++++++++++++++++ arch/arm/mach-mvebu/Kconfig | 7 ++ 3 files changed, 163 insertions(+) create mode 100644 arch/arm/dts/armada-385-amc.dts (limited to 'arch') diff --git a/arch/arm/dts/Makefile b/arch/arm/dts/Makefile index 1d41d48555..df57288076 100644 --- a/arch/arm/dts/Makefile +++ b/arch/arm/dts/Makefile @@ -70,6 +70,7 @@ dtb-$(CONFIG_ARCH_MVEBU) += \ armada-375-db.dtb \ armada-388-clearfog.dtb \ armada-388-gp.dtb \ + armada-385-amc.dtb \ armada-xp-gp.dtb \ armada-xp-maxbcm.dtb \ armada-xp-synology-ds414.dtb \ diff --git a/arch/arm/dts/armada-385-amc.dts b/arch/arm/dts/armada-385-amc.dts new file mode 100644 index 0000000000..858138a337 --- /dev/null +++ b/arch/arm/dts/armada-385-amc.dts @@ -0,0 +1,155 @@ +/* + * Device Tree file for Marvell Armada 385 development board + * (DB-88F6820-AMC) + * + * Copyright (C) 2014 Marvell + * + * Gregory CLEMENT + * + * This file is dual-licensed: you can use it either under the terms + * of the GPL or the X11 license, at your option.
