National Semiconductor GPIO common access methods.
The GPIO units on these chips have the same pin architecture, but the access methods differ. Thus, scx200_gpio and pc8736x_gpio implement their own versions of these routines; and use the common file-operations routines implemented in nsc_gpio module.
