I think that we should really move all those clock controller yaml files to their
proper directory, which would be
Documentation/devicetree/bindings/clock/
...because those are clock controllers anyway and the fact that they do also
provide a reset controller doesn't really justify having them in arm/mediatek.
Besides, I would appreciate if you could also move mt8186/92/95 and eventual
others that are there to clock/.
Yes, please move it.

+title: MediaTek PCIESYS controller
+
+description:
+ The MediaTek PCIESYS controller provides various clocks to the system.
+
+maintainers:
+ - Matthias Brugger <matthias.bgg@xxxxxxxxx>
+
+properties:
+ compatible:
+ items:
+ - enum:
+ - mediatek,mt7622-pciesys
+ - mediatek,mt7629-pciesys
+ - const: syscon
I know that there's syscon all over the place and, even if I admit I didn't check,
I am fairly sure that there's absolutely no reason to have syscon there, and that
the syscon compatible never did anything for (most of, or all of) those clock
controllers, at all.
I'm not sure - though - if removing syscon during the txt->yaml conversion is
acceptable (yeah we'd be cheating a bit), but something makes me say it is, because
the bindings couldn't validate before that one as well.
As long as you state why you are removing it in the commit msg.
Of course you'd have to remove the syscon compatible from the affected device trees
as well as omitting it here.
You could also do 'minItems: 1' and 'deprecated' in the 2nd item.
That too. Yes. But I still really want to see the syscon compatible removed from
the device trees on those nodes because it doesn't make any sense to have it :-)
However, to be sure that we're doing the right thing here, I have to summon someone
that can actually give a definitive answer to what I just said.....
Krzysztof, please? :-)
