Banana Pi M2 Zero board is a H2+-based board by Sinovoip, with a form factor and GPIO holes similar to Raspberry Pi Zero. 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 <icenowy@aosc.io> --- Changes in v5: - Fix SPDX license identifier position. Changes in v4: - Use SPDX license identifier. 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 | 125 +++++++++++++++++++++ 2 files changed, 126 insertions(+) create mode 100644 arch/arm/boot/dts/sun8i-h2-plus-bananapi-m2-zero.dts
