nsc_gpio_ops Struct Reference

#include <nsc_gpio.h>

List of all members.

Detailed Description


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.

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.
