I'm undecided about this ... and while thinking about this, realized that we already have some changes doing that in the tree. To explain, in general the pinctrl names should come from the names used in the actual device schematics, as this makes it easier to find and compare them between devicetree and schematics files. So creating an arbitrary foo_led_pin pinctrl instead breaks this searchability which I'd really like to keep.
