There is no subsystem "pmic".

Just fold the device to the parent node.

Filename matching one of the compatibles, e.g. the oldest one.
Yeah but besides that I don't see valid reasons why this should be a different
binding (and also why this should use a different driver, fwiw) - when it can
most probably just extend the current PMIC MFD driver... and the same goes for
the PMIC AUXADC: there's a mt6359-auxadc binding and driver that can be extended
to 6363 and 6373 rather easily.
There's nothing "really special" about those.....

I don't get why they are in the same schema. It would result in
unnecessary big if:then with half of children not applicable for other
variants.

Sort these with alphanumeric order.
