My non-native english suggests:

- pinctrl-single,power-source-mask : mask for setting the power source in
  the pinmux register

> +- pinctrl-single,power-source : value of setting power source field
> +  in the pinmux register

- pinctrl-single,power-source : value for setting the power source field
  in the pinmux register

And the same for the rest.

I suggest you update the above to say:

Optional sub-node: In case some pins can be configured as GPIO in the pinmux
register. If both the GPIO number and pin base of those pins are in ascending
order, these pins can be defined as a GPIO range.

Then maybe clarify the sub-node part a bit, or just leave it out? Actually the
"ascending order" part is a bit unclear to me too..
