This looks good on a first glance, but seems to miss the DVFS bits? So you
would need to #include "sun50i-h616-cpu-opp.dtsi" and specify the cpu0
power supply rail, otherwise you will be stuck at 1GHz.

Or is there any issue preventing you doing this?

Is this missing some copyright notice here?

Would it make sense to add the mmc1 node here, even if there is no driver
in Linux atm for the WiFi chip? Thanks to SDIO we wouldn't need a
compatible string, I think. This would also then allow us to describe the
connected GPIOs.

And does the box have Bluetooth?

Cheers,
Andre
