Fair enough. For GPIO, using the Linux GPIO driver as a back-end for
the ASL means that we don't have to duplicate the Linux GPIO driver in
firmware, and it also allows a high degree of flexibility. That sounds
like highly desirable features for any device support, including pin
control.
I don't really understand ACPI/ASL enough to really have much insight in
this area, but I've been waiting over six months for someone ... anyone
... to do someone on this area. So I'm kinda stuck -- I have a vested
interested in this area, and yet I'm not in a position to contribute much.
