Yes, correct. This patch set is for the original M6 board. V1 if you like.

I did notice there was a new version, but I hadn't given it much thought.

Yes, I think you are right.

How about this setup:
rk3588s-nanopi-m6.dtsi
rk3588s-nanopi-m6v1.dts
rk3588s-nanopi-m6v2.dts
This mimics the setup for the R6 series boards with rk3588s-nanopi-r6.dtsi
and rk3588s-nanopi-r6[cs].dts.

Note that I will not make the v2 board part of this patchset since I
am unable to
test it. But as you said we can take it into account now.

If you have no objections I will integrate this setup into versions 2
of this patch set.
Thanks for the feedback!

I did a quick comparison of the schematics and noticed the following
differences:
* New CODEC; ES8389
* A new "User" button connected to a gpio line.
* Different USB 2.0 hub: CH334P (may not be relevant for DT)
* Different USB PD power solution (not relevant for DT)
