The NanoPi-A64 has an on-board WiFi/Bluetooth combo chip, connected
to the usual MMC1 and UART1. The power is provided by the always-on
VCC_SYS_3.3V, but it uses pin L2 to enable the regulator.

Add the respective nodes to the DT to make it usable.

NanoPi A64 has rtl8189 Ethernet chip.

Good point, thanks for mentioning it (though I guess you mean WiFi
chip).
Do you have the board? Do you have WiFi working?
From a very brief look over the tree I don't see any explicit driver
for
an SDIO based 8189 variant, but other boards claiming to have a 8189
seem to just not provide a compatible at all. Does that actually work?

Work with out-of-tree drivers by Hans de Goede.

It would be great if you could share some insight here!

Thanks!
Andre.
