Add support for the LinkSprite pcDuino 3 Nano board. This is a low-cost Allwinner A20 board with Arduino-style GPIO headers; it features 1G RAM, 4G NAND flash, 1 micro-SD, 2 USB sockets, 1 micro USB socket for OTG and another for power in, HDMI, SATA, 5V power for SATA devices, gigabit Ethernet, an IR receiver, 3.5mm audio out and a MIPI camera connector. For more details, see: http://linux-sunxi.org/LinkSprite_pcDuino3_Nano Changes in v3: - rename LEDs to pcduino3-nano:green:usr[12] - remove optional features on Arduino headers (i2c2, spi0, uart2) Signed-off-by: Adam Sampson <ats@xxxxxxxxx> --- arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/sun7i-a20-pcduino3-nano.dts | 191 ++++++++++++++++++++++++++ 2 files changed, 193 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/sun7i-a20-pcduino3-nano.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 7df26a2..c025724 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -479,7 +479,8 @@ dtb-$(CONFIG_MACH_SUN7I) += \ sun7i-a20-olinuxino-lime.dtb \ sun7i-a20-olinuxino-lime2.dtb \ sun7i-a20-olinuxino-micro.dtb \ - sun7i-a20-pcduino3.dtb + sun7i-a20-pcduino3.dtb \ + sun7i-a20-pcduino3-nano.dtb dtb-$(CONFIG_MACH_SUN8I) += \ sun8i-a23-ippo-q8h-v5.dtb \ sun8i-a23-ippo-q8h-v1.2.dtb diff --git a/arch/arm/boot/dts/sun7i-a20-pcduino3-nano.dts b/arch/arm/boot/dts/sun7i-a20-pcduino3-nano.dts new file mode 100644 index 0000000..632b8a9 --- /dev/null +++ b/arch/arm/boot/dts/sun7i-a20-pcduino3-nano.dts @@ -0,0 +1,191 @@ +/* + * Copyright 2015 Adam Sampson <ats@xxxxxxxxx> + * + * This file is dual-licensed: you can use it either under the terms + * of the GPL or the X11 license, at your option.
