This adds the device tree for the Toradex Iris carrier board used together with a Colibri T20 512MB COM. The Iris has the following features, in brackets the current status: - DVI and VGA output through DVI-I connector (DVI-D enabled and tested) - LVDS output - 1 USB host port (enabled and tested) - 1 USB OTG port (enabled) - 100 MBit Ethernet (enabled and tested) - 5 UART ports (2 on 10way headers enabled and tested) - 1 MicroSD Slot (enabled and tested) - Audio connectors (enabled, only HP out and Line-in tested) - i2c RTC - GPIO connector (enabled, only sparsely tested) - external i2c bus - 4 PWM out - analog in Signed-off-by: Lucas Stach <dev@lynxeye.de> --- Documentation/devicetree/bindings/arm/tegra.txt | 1 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/tegra20-iris-512.dts | 88 +++++++++++++++++++++++++ 3 files changed, 90 insertions(+) create mode 100644 arch/arm/boot/dts/tegra20-iris-512.dts
