The MangoPi MQ-R is a small SBC with the Allwinner T113-s3 SoC.
The SoC features two Arm Cortex-A7 cores and 128 MB of co-packaged DDR3
DRAM. The board adds mostly connectors and the required regulators, plus
a Realtek RTL8189FTV WiFi chip.
Power comes in via a USB-C connector wired as a peripheral, and there is
a second USB-C connector usable as a host port.

Generic node names, so matching style of other - with regulator prefix.
