Oh that depends. I have hade lectures on pin control at the embedded
systems conference and there I treat it as a neutral term referring to this
kind of electronic constructions.

However how something is established in OF ontology I don't know so
you might be right there, but you're making it sound like
Documentation/devicetree/bindings/pinctrl/
should not exist and all those bindings be moved to gpio or
something if the assumption that "pin control" or the abbreviation
pinctrl is a Linux-specific term. (Which is not my interpretation.)

The commit message should state what regression it is actually
solving. Which is that when using a non-DT boot, the ABx500
pinctrl devices are not probed, right?

Apart from the commit message:
Acked-by: Linus Walleij <linus.walleij@xxxxxxxxxx>

On the patch as such.

Yours,
Linus Walleij
