Many thanks for sending this upstream, this looks very good overall,
only some small things below...

I don't think we need the serial1 alias? Bluetooth should work even
without knowing the ttyS<x> device name, shouldn't it?

But you should add an alias for the WiFi (ethernet0 = &brcm;), so that
U-Boot assigns an ideally unique MAC address.

The rest looks correct, from a pure upstream DT perspective, and by
comparing it to other H6 .dts files, even though I cannot test it, of
course. But I trust you that those things you mentioned work.

So with the aliases changed:
