The mt6357 is a subnode of pwrap node. Previously, the documentation
only included a note in the description of mt6357. This change adds the
appropriate $ref for pwrap to ensure clarity and correctness.

  $ref: /schemas/soc/mediatek/mediatek,pwrap.yaml

Additionally, the indentation for the pmic section has been adjusted
to match the corresponding structure.

Heh? The schema described mt6357, not pwrap. Why are you changing it?

How does this schema is being selected without compatible?

With the diff it is tricky to say what you are doing, but it feels
wrong. I don't understand the rationale, the problem being fixed here,
and considering unusual diff, this just looks wrong approach.

Bindings do not work like that - you do not reference the parent inside
the child. There is nowhere example for that, so I have no clue how did
you come up with it.

Best regards,
Krzysztof

I think this change is wrong and the existing binding is fine.
Adding the ref overcomplicates the binding completely, and stating that
this is a child node of another device is sufficient.

Instead, if anything, the pwrap binding should have a ref to /this/
binding.

Thanks,
Conor.

Yes or list allowed compatibles for child node.

Thanks for the clarification of this parent-child relationship of the 
binding. Will apply to further conversion tasks.

There are many PMIC devices belongs to the pwrap bindings. Hope I'll 
have time to fix this soon.
