gscsio - National Semiconductor Geode SC1100 Super I/O
gscsio* at isa?
The gscsio driver provides support for the National Semiconductor Geode
SC1100 System-on-Chip Super I/O module. The Super I/O (SIO)
one serial port, an infrared communication port,
interface (ACB) ports, system wakeup control (SWC),
and a realtime
clock (RTC). Only the ACCESS.bus interface is currently supported.
ACB is a two-wire synchronous serial interface compatible
Philips' I2C bus, and can be accessed through the iic(4)
gscsio driver programs the ACB port to work with a standard
iic(4), intro(4), isa(4)
The gscsio driver first appeared in OpenBSD 3.6.
The gscsio driver was written by Alexander Yurchenko
