[PATCH] dt-bindings: soc: renesas: Move renesas.yaml from arm to soc

[PATCH] dt-bindings: soc: renesas: Move renesas.yaml from arm to soc

[Lad Prabhakar]

renesas.yaml lists out all the Renesas SoC's and the platforms/EVK's which
is either ARM32/ARM64. It would rather make sense if we move renesas.yaml
to the soc/renesas folder instead. This is in preparation for adding a new
SoC (RZ/Five) from Renesas which is based on RISC-V.

While at it drop the old entry for renesas.yaml from MAINTAINERS file and
there is no need to update the new file path of renesas.yaml as we already
have an entry for Documentation/devicetree/bindings/soc/renesas/ folder.

Please post this as part of the above.

bindings/soc/ is just a dumping ground for stuff that doesn't fit 
anywhere. We've mostly cleaned bindings/arm/ of that, so I don't really 
want to start that again. I would propose bindings/board/ instead if we 
move in this direction.

Sure, I just wanted to get some feedback on this so had it posted separately.

OK. So to clarify, how do we separate it further bindings/board/<based
on SoC vendor> or bindings/board/<board manufacturer>?

The latter doesn't work with how the schemas are structured.

Note that the target of this move is not .../bindings/soc/, but
.../bindings/soc/renesas/, so it's a bit less of a dumping ground.
Perhaps this is also a good opportunity to split renesas.yaml per
family or product group
(renesas,{rmobile,rcar-gen[1234],rza,rzg,rzn,...}.yaml?
A fine-grained split may cause headaches with RZ/G2UL and RZ/Five
sharing the same SoC Base, but a coarse-grained split keeping all RZ/G
(after all RZ/Five is part of RZ/G) or even all RZ series together should work.

.../bindings/board has the issue with the same boards used with
multiple pin-compatible SoCs, SiPs, and SoMs.

bindings/soc/ means bindings/soc/vendor/, so it means bindings/soc/renesas/.

There are no files in bindings/soc/ directly.

Therefore it is still dumping ground.
