@Emil, I feel like I have to ask given the 2022 date, but should this
stuff be attributed to your canonical address or is this fine?

Other than that, a cursory check /looks/ fine, other than the:

If you remove the clock-frequency = <0> bit, dtb validation will force
people to set the value in jh7110-board.dts which I'd prefer to rely on
than a comment.

Glad to see you sorted out the clock/reset stuff too!

Thanks,
Conor.

Yeah, this is fine. I did this on my own time before I was actually
tasked with working on the JH7110 based boards.

Please sort these nodes after their address like the jh7100.dtsi.
That is sort the nodes after @<number>.
