   4 Subject: [PATCH 031/117] riscv: dts: allwinner: Add MangoPi MQ Pro devicetree
   5
   6 The MangoPi MQ Pro is a tiny SBC with a layout compatible to the
   7 Raspberry Pi Zero. It includes the Allwinner D1 SoC, 512M or 1G of DDR3,
   8 and an RTL8723DS-based WiFi/Bluetooth module.
   9
  10 The board also exposes GPIO Port E via a connector on the end of the
  11 board, which can support either a camera or an RMII Ethernet PHY. The
  12 additional regulators supply that connector.
