Signed-off-by: Bert Vermeulen --- Changes from v3: - added comment noting eth1 is connected to switch as well Changes from v2: - added linksys to filename - added make rule Changes from v1: - changed console to stdout-path - removed unnecesarry @0 from dsa node, and fixed dsa/switch node - fixed partitions according to the official docs - prefer node labels rather than full hierarchy where possible arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/kirkwood-linksys-viper.dts | 237 +++++++++++++++++++++++++++ 2 files changed, 238 insertions(+) create mode 100644 arch/arm/boot/dts/kirkwood-linksys-viper.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 95c1923..feeb3f9 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -199,6 +199,7 @@ dtb-$(CONFIG_MACH_KIRKWOOD) += \ kirkwood-linkstation-lswsxl.dtb \ kirkwood-linkstation-lswvl.dtb \ kirkwood-linkstation-lswxl.dtb \ + kirkwood-linksys-viper.dtb \ kirkwood-lschlv2.dtb \ kirkwood-lsxhl.dtb \ kirkwood-mplcec4.dtb \ diff --git a/arch/arm/boot/dts/kirkwood-linksys-viper.dts b/arch/arm/boot/dts/kirkwood-linksys-viper.dts new file mode 100644 index 0000000..0f4631f --- /dev/null +++ b/arch/arm/boot/dts/kirkwood-linksys-viper.dts @@ -0,0 +1,237 @@ +/* + * kirkwood-viper.dts - Device Tree file for Linksys viper (E4200v2 / EA4500) + * + * (c) 2013 Jonas Gorski + * (c) 2013 Deutsche Telekom Innovation Laboratories + * (c) 2014 Luka Perkov + * (c) 2014 Randy C.
