This makes use of the gpio-ranges feature that connects GPIO
controllers and PINMUX controllers.
In da850.dtsi, pinctrl-single,gpio-range is added to the pinmux node
and gpio-ranges is added to the GPIO node. Unfortunately, the way the
pinctrl-single driver enumerates the pins (starting with LSB) causes
them to be in reverse order compared to the way the gpios are assigned.
As a result, we have to declare the mapping for each GPIO individually.
This also lets us remove all of the GPIO pinmuxes from
da850-lego-ev3.dts. (Other da850 boards do not currently have any
GPIO pinmuxes declared.)

Looks good to me too. And quite painstakingly done!
I suppose this needs to wait a bit due to the dependencies? Let me know
once its okay to merge.
The dependencies are in v4.17-rc1 so you can pick up this patch now.
