From 76b92b4043f2303b443645b5609a8867e8a8b5d7 Mon Sep 17 00:00:00 2001 From: Bastian Hecht Date: Wed, 17 Apr 2013 12:34:06 +0200 Subject: ARM: shmobile: armadillo800eva: Reference DT implementation Provide alternate board code for the Armadillo800EVA to demonstrate how DT may be used given the current state of driver device tree support. This is intended to act as a reference for mach-shmobile developers. This a rather bare bone version with the following devices supported: - GIC - irqpins - i2c0/1 - touchscreen Signed-off-by: Bastian Hecht Signed-off-by: Simon Horman --- arch/arm/boot/dts/Makefile | 1 + .../boot/dts/r8a7740-armadillo800eva-reference.dts | 45 ++++++++++++++++++++++ 2 files changed, 46 insertions(+) create mode 100644 arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts (limited to 'arch/arm/boot') diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index b9f7121e6ec..cb312592342 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -162,6 +162,7 @@ dtb-$(CONFIG_ARCH_U8500) += snowball.dtb \ dtb-$(CONFIG_ARCH_SHMOBILE) += emev2-kzm9d.dtb \ r8a7740-armadillo800eva.dtb \ r8a7778-bockw.dtb \ + r8a7740-armadillo800eva-reference.dtb \ r8a7779-marzen-reference.dtb \ r8a7790-lager.dtb \ sh73a0-kzm9g.dtb \ diff --git a/arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts b/arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts new file mode 100644 index 00000000000..09ea22c2635 --- /dev/null +++ b/arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts @@ -0,0 +1,45 @@ +/* + * Reference Device Tree Source for the armadillo 800 eva board + * + * Copyright (C) 2012 Renesas Solutions Corp. + * + * This file is licensed under the terms of the GNU General Public License + * version 2.
