From bf78b2717d3279e8dc74fa3bb69096ced7d8afda Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Fri, 5 Sep 2014 10:18:38 +0200 Subject: arm: tegra: initial support for apalis t30 This patch adds board support for the Toradex Apalis T30 a computer on module which can be used on different carrier boards. For the sake of ease of use we do not distinguish between different carrier boards for now as the base module features are deemed sufficient enough for regular booting. The following functionality is working so far: - eMMC boot and environment storage - Gigabit Ethernet (once Thierry's PCIe as well as my E1000 resp. i210 fixes hit mainline) - MMC/SD cards (both 8-bit as well as 4-bit slot) - USB client/host (dual role port as client e.g. for DFU/UMS, other two ports as host) Signed-off-by: Marcel Ziswiler Acked-by: Stephen Warren Signed-off-by: Tom Warren --- arch/arm/dts/Makefile | 1 + arch/arm/dts/tegra30-apalis.dts | 300 ++++++++++++++++++++++++++++++++++++++++ 2 files changed, 301 insertions(+) create mode 100644 arch/arm/dts/tegra30-apalis.dts (limited to 'arch/arm/dts') diff --git a/arch/arm/dts/Makefile b/arch/arm/dts/Makefile index c37580ed84..c34606334d 100644 --- a/arch/arm/dts/Makefile +++ b/arch/arm/dts/Makefile @@ -22,6 +22,7 @@ dtb-$(CONFIG_TEGRA) += tegra20-harmony.dtb \ tegra20-ventana.dtb \ tegra20-whistler.dtb \ tegra20-colibri_t20_iris.dtb \ + tegra30-apalis.dtb \ tegra30-beaver.dtb \ tegra30-cardhu.dtb \ tegra30-colibri.dtb \ diff --git a/arch/arm/dts/tegra30-apalis.dts b/arch/arm/dts/tegra30-apalis.dts new file mode 100644 index 0000000000..5c717e2c4d --- /dev/null +++ b/arch/arm/dts/tegra30-apalis.dts @@ -0,0 +1,300 @@ +/dts-v1/;
