I'm confused. User of this patch is pinctrl-broxton driver.
It's in upstream.
Using GPIOs from it is something as done in a few drivers already
(Assuming we have no resources described in the ACPI). I.e. you need to
register in board file the GPIO mapping table with help of
devm_acpi_dev_add_driver_gpios() and use one of gpiod_get() family of functions
to request it.
In case of LEDs you simple describe GPIO device name in lookup table and
that's it. The drivers/platform/x86/pcengines-apuv2.c not the best but
will give you an idea how to use "leds-gpio" driver in board files.
