No, that's my point.  I was expecting the pinmux functions of the 
pinctrl driver are used by ACPI, but apparently they aren't, and that's 
why I'm asking.  I'm wondering why a pinctrl driver for an ACPI platform 
should be defining pinmux function groups.  I haven't gotten a straight 
answer to that question.
