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.

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.

Sorry to be a bit picky about this, but this should be your very first
line, see arch/arm/boot/dts/sun7i-a20-olimex-som204-evb.dts for example.
