I do not like this, as this is not HW feature, so DT may not be right
approach.

So I will dig more from either runtime or Compile time option to use
regmap_ Vs raw read/writes.

Can't you just check if the pinctrl node has compatible = "syscon"
property?

A compile time option won't work for sure. I don't know what you
would check at runtime as you do not know what the bus is behind
syscon.


Although, I haven't gone through syscon, but not sure whether syscon
would be useful.

As you rightly stated, we need to know the bus behind regmap.

Thanks,
