Subject: [PATCH v2 08/12] riscv: dts: allwinner: Add MangoPi MQ Pro devicetree
The MangoPi MQ Pro is a tiny SBC with a layout compatible to the
Raspberry Pi Zero. It includes the Allwinner D1 SoC, 512M or 1G of DDR3,
and an RTL8723DS-based WiFi/Bluetooth module.
The board also exposes GPIO Port E via a connector on the end of the
board, which can support either a camera or an RMII Ethernet PHY. The
additional regulators supply that connector.
Signed-off-by: Samuel Holland <samuel@...lland.org>

Changes in v2:
- Added LED (GPIO shared between onboard LED and backlight regulator)
