Drop the $ref. It will get validated by matching the pmic compatible.

Should be an extra commit.

Implicit to the first line.

Missing mediatek,mt8186-pwrap

> +              - mediatek,mt8188-pwrap

mt8188 has mt8195 as fallback, that must be kept as otherwise the driver does 
not bind.

Not in the original txt binding, maybe add that in a first patch and then convert.

I think, instead of fixing a deprecated file, I should fix it directly
here. Actually, I forgot to
mention this change in the commit message, but I will add it for the
next version.

Thanks,

It was explained in pwrap.txt. I've done extra work for the previous
version but removed it for the current one. I think I can remove this
line from the commit message.
