Wouldn't it be simpler to fix the GPIO binding documentation and
gpiod_get() code to allow the -gpio suffix in addition to -gpios? It
always struck me as silly that the binding required a plural property
name when only a single entry made sense.

(For something like "clocks", since the property name applies to any
clock, and there certainly can be many clocks, a plural property name
makes sense. However, since each type of GPIO is "foo-gpios" rather than
an "foo" entry in "gpios", that same argument doesn't apply, and a
singular property name seems much more correct).
