NAME

       gpio_87317 - General purpose I/O driver for SuperIO

DESCRIPTION

       The gpio_87317 driver is the general purpose I/O driver for the National Semiconductor SuperIO (PC87317) chipset. It supports remote system
       controller (RSC) administration via an interface to the SuperIO's general purpose I/O bits.

NAME

       smbus - System Management Bus controller driver

DESCRIPTION

       The  smbus driver is a I2C (Inter IC) nexus driver that allows the system to communicate with various system	 component chips. SMBus is
       a two-wire control bus based on the I2C protocol through which systems can communicate with various I2C devices connected to the bus.

       The smbus driver supports byte and block level transfer based on interrupt and polled mode.
