+
+ National Semiconductor GPIO common access methods.
+
+ struct nsc_gpio_ops abstracts the low-level access
+ operations for the GPIO units on 2 NSC chip families; the GEODE
+ integrated CPU, and the PC-8736[03456] integrated PC-peripheral
+ chips.
+
+ 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.
+
+ Copyright (c) 2005 Jim Cromie <jim.cromie@xxxxxxxxx>
+
+ NB: this work was tested on the Geode SC-1100 and PC-87366 chips.
+ NSC sold the GEODE line to AMD, and the PC-8736x line to Winbond.
