Just pull all these down two levels and make them one device
each instead of having them inside the pin controller node
like this.

Then make a pin controller node separately, it can reference the
pin controller by phandles if necessary, and use the standard
gpio-ranges property to cross make GPIO and pin control.

It seems you driver is similar to for example the
drivers/pinctrl/nomadik/* pin controller.

Look in arch/arm/boot/dts/ste-dbx500.dtsi for examples,
NB: I'm not fully using standard bindings in it, because they
were not invented at the time.

Yours,
Linus Walleij
