* 2.6 port by Matt Porter <mporter@kernel.crashing.org>
*
* The documentation describes this as an SMBus controller, but it doesn't
* understand any of the SMBus protocol in hardware. It's really an I2C
* controller that could emulate most of the SMBus in software.
*
* This is just a skeleton adapter to use with the Au1550 PSC
* algorithm. It was developed for
