Jacopo, any opinion on this ? Should it be conevrted to an overlay, or
dropped ?

I don't have access to this panel any more. I'm fine dropping this
.dtsi, it can always be resurrected and converted to an overlay if
someone needs it.

This would be nice to turn into an overlay, but I'm not sure anyone
still cares.

I started to write a reply saying I care about this one for V3M and that
it should be converted to a .dtso. I then looked at the last time I used
it, ~2 years ago, and the next ting I would need it for is to play with
the GMSL framework being worked on by Cosmin and streams whenever that
is merged. I also looked at the file itself and there is some work
needed split it into more useful .dtso structure.
Inertia hit and I deleted the reply thinking I will do a new .dtso when
I test the above as the verification of a new overlay alone will require
the same setup and verification work.
tl;dr; I care about the function, I'm OK with removing the .dtsi; I will
recreate the functionality as .dtso files in future.

The lot of the above are for SoCs that exist and there could well be users using them who haven't upstreamed a dts.
I'd convert them to overlays but they all make use of /delete-node/ which as far as I understand isn't supported in overlays.
Is there another option rather than removing these dtsi files?
Kind regards, Chris

While I do understand your point, these might be used by customers of
the SoCs. Hence they can be considered part of the "stable DT ABI",
and removing them can cause issues downstream.
At least for the r8a779m* parts, I do have local patches in my tree,
so I would notice any future build breakages (most files are rather
simple, so unlikely to break, though).
Shall we just upstream .dts files using these .dtsi files (cfr. the
existing arch/arm64/boot/dts/renesas/r8a779m*dts)? AFAIK none of
the missing board/SoC-combos actually exist as products, but someone
might create one locally by replacing the SoC on an existing board,
as they are pin-compatible variants.
There is a similar story for the r9a0* parts: they are variants with
less CPU cores, which may end up in actual products. We could add
.dts files using them, to make sure no build breakage is introduced.
Please let me know how you would like to proceed.
Thanks!

Converting to overlays is not suitable here, as these do represent base
SoC functionality, not an add-on.
Besides, overlays also have the "must have at least one user" rule.

DTBs are the ABI, not .dtsi. The compatible in these is not validated
and isn't valid. We could simply restructure .dtsi files in a way that
breaks downstream and wouldn't give it a second thought.

You probably could restructure these where you include the subset
.dtsi and then add nodes rather than delete them. For the ones that
just override the compatible with an invalid value that has to be
overridden by the board dts anyways, there's little value to them.
Just drop them or add a proper board.

If these are all just binned parts, I would not have separate SoC
compatibles for them.
