It features: - Allwinner H2+ SoC - Single-chip (16-bit) 512MiB DDR3 DRAM - Ampak AP6212 Wi-Fi/Bluetooth module - MicroSD slot - Two MicroUSB Type-B ports (one can only be used to power the board and the other features OTG functionality) - Two keys, a reset and a GPIO-connected key. - HDMI Type-C (miniHDMI) connector connected to the HDMI part of H2+. - CSI connector to connect the camera sensor provided by Sinovoip. Signed-off-by: Icenowy Zheng --- Changes in v3: - Add comments about Vbus problem in &usbphy node. Changes in v2: - Use high active SD card detect on the production batch. arch/arm/boot/dts/Makefile | 1 + .../boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts | 162 +++++++++++++++++++++ 2 files changed, 163 insertions(+) create mode 100644 arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 0bb8db33704a..937a8768671f 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -962,6 +962,7 @@ dtb-$(CONFIG_MACH_SUN8I) += \ sun8i-a83t-cubietruck-plus.dtb \ sun8i-a83t-tbs-a711.dtb \ sun8i-h2-plus-orangepi-r1.dtb \ + sun8i-h2-plus-bananapi-m2-zero.dtb \ sun8i-h2-plus-orangepi-zero.dtb \ sun8i-h3-bananapi-m2-plus.dtb \ sun8i-h3-beelink-x2.dtb \ diff --git a/arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts b/arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts new file mode 100644 index 000000000000..5bc182ddc5f7 --- /dev/null +++ b/arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts @@ -0,0 +1,162 @@ +/* + * Copyright (C) 2017 Icenowy Zheng + * + * Based on sun8i-h3-bananapi-m2-plus.dts, which is: + * Copyright (C) 2016 Chen-Yu Tsai + * + * This file is dual-licensed: you can use it either under the terms + * of the GPL or the X11 license, at your option.
