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
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 100kHz.
