Correction: you should be using the property "pinmux", because you
are setting group and function at the same time.

See for example:
include/dt-bindings/pinctrl/mt65xx.h

And how that is used in:
arch/arm/boot/dts/mt2701-pinfunc.h
arch/arm/boot/dts/mt2701-evb.dts

The docs are here:
Documentation/devicetree/bindings/pinctrl/pinctrl-mt65xx.txt

I'm sorry that "pinmux" is not part of the generic documentation, it'd be
great if you would like to add it with a patch.

Yours,
Linus Walleij
