The Radxa ROCK 5B+ is an upgraded version of the Radxa ROCK 5B.

This patch series introduces a shared .dtsi that can be used on the
new Radxa ROCK 5B+, the existing Radxa ROCK 5B, and the upcoming Radxa
ROCK 5T.

This patch series includes "arm64: dts: rockchip: Add USB-C support to
ROCK 5B" by Sebastian Reichel[1].

This one doesn't look equivalent to the existing ROCK 5B device tree
after your changes (I've noticed in particular that fan cooling levels
are different - but that's just the part I remember well since I
modified it earlier, there might be more differences).

Would you mind rearranging the patches so that the split of ROCK 5B
dts into a common .dtsi and per-board .dts additions could be made
one-to-one equivalent without functional changes, and then add ROCK
5B+ and any other required changes on top of that?

See what Dragan did where he prepared parent .dtsi for per-variant OPPs [1]

Just a brief note that I agree with Alexey's recommendation above.
These patches should be reworked in a way that makes the transition
to using the shared dtsi file much more obvious.

Besides making these changes easier to review that way, and giving
better chances to ensuring there are no issues that managed to slip
through the cracks, it will also be much easier later to track down
any possible regressions, in case they eventually are discovered.

Thanks for pointing!

My priority goal is to add support for ROCK 5B+ and 5T. This time, I 
will not make any changes to ROCK 5B so as not to break it. Therefore, I 
will drop PATCH 3/3.

(I would like to make changes to ROCK 5B at some point.)

I see, but I think that just dropping the patch 3/3 wouldn't be the
best possible option.  That way you'd end up with a "dangling" dtsi
file, used by just one board dts file, which is a bit suboptimal.

I'd suggest that you actually do it the right way, so to speak, by
actually converting the ROCK 5B dts file to use the shared dtsi file
in a way that makes the transition more obvious and, as a result,
easier to review, as already suggested above.

As another option, I'm going to ask Radxa for a sample ROCK 5B+ board
soon, for my Rockchip SoC binning project, and if I actually get it,
I could take over this series, to help you that way with getting the
patch series in better shape.

So please ignore this patch series until I can add ROCK 5T, which will 
be available soon. (Maybe...)

I'm sending v2 due to a small fix, please ignore it.

If I have enough time to fix the ROCK 5B dts, I will do it.
