driver provides support for the
National Semiconductor Geode SC1100 System-on-Chip Super I/O module. The Super
I/O (SIO) module incorporates one serial port, an infrared communication port,
two ACCESS.bus interface (ACB) ports, system wakeup control (SWC), and a
real-time clock (RTC). Only the ACCESS.bus interface is currently supported.
ACB is a two-wire synchronous serial interface compatible with the Philips' I2C
bus, and can be accessed through the
driver programs the ACB port to work
with a standard I2C frequency 100kHz.
