The gscsio 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
ACB is a two-wire synchronous serial interface compatible with the
Philips' I2C bus, and can be accessed through the iic(4) framework. The
gscsio driver programs the ACB port to work with a standard I2C frequency
