From 57c0f8c9c45365d167f8606dad7fde9565432b7a Mon Sep 17 00:00:00 2001 From: Dalon Westergreen Date: Wed, 8 Jul 2015 16:48:49 -0700 Subject: [PATCH] ARM: dts: socfpga: Add support of Terasic DE0 Atlas board The Terasic DE0 Atlas board is also known as the DE0-Nano board. This patch adds the DTS board file for the DE0-Nano Sockit board, and not the DE0 Nano "Development Board". Signed-off-by: Dalon Westergreen Signed-off-by: Dinh Nguyen --- v3: Updated skew settings for the gmac1 node as this board is using the KSZ9031 PHY instead of the 9021 PHY. v2: use stdpath-out for console and remove comment regarding u-boot ethaddr --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/socfpga_cyclone5_de0_sockit.dts | 111 ++++++++++++++++++++++ 2 files changed, 112 insertions(+) create mode 100644 arch/arm/boot/dts/socfpga_cyclone5_de0_sockit.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 246473a..29e33aa 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -522,6 +522,7 @@ dtb-$(CONFIG_ARCH_SOCFPGA) += \ socfpga_arria5_socdk.dtb \ socfpga_arria10_socdk_sdmmc.dtb \ socfpga_cyclone5_socdk.dtb \ + socfpga_cyclone5_de0_sockit.dtb \ socfpga_cyclone5_sockit.dtb \ socfpga_cyclone5_socrates.dtb \ socfpga_vt.dtb diff --git a/arch/arm/boot/dts/socfpga_cyclone5_de0_sockit.dts b/arch/arm/boot/dts/socfpga_cyclone5_de0_sockit.dts new file mode 100644 index 0000000..555e9ca --- /dev/null +++ b/arch/arm/boot/dts/socfpga_cyclone5_de0_sockit.dts @@ -0,0 +1,111 @@ +/* + * Copyright Altera Corporation (C) 2015.
