I take it those are connected to a hub chip, and the micro-USB socket is
connected as a true OTG socket?
So you should enable the usb_otg node, but without the host mode
override we use for the Pine64.

It looks like Wifi + BT are soldered on the board, so you should at
least enable the proper UART connected to the Bluetooth chip, probably
also MMC1 (which is surely connected to the WiFi chip) should be
described as an SDIO node.

I guess the board uses the AXP803 as well? You might want to coordinate
with Icenowy what to do to describe this as well, given that her patches
might go in before.

Cheers,
Andre.
