NAME
     piixpm - Intel PIIX SMBus controller

SYNOPSIS
     piixpm* at pci?
     iic* at piixpm?

DESCRIPTION
     The piixpm driver provides support for the Intel PIIX and compatible
     Power Management controller.  Only the SMBus host interface is supported
     and can be used with the iic(4) framework.

     Supported chipsets:

	   o   ATI SB200, SB300, SB400, SB600, SB700, SB800
	   o   Intel 82371AB (PIIX4), 82440MX

HISTORY
     The piixpm driver first appeared in OpenBSD 3.7 to provide support for
     the power management (ACPI) timer.	 In OpenBSD 3.9, power management
     support was dropped in favor of acpitimer(4) and SMBus functionality was
     added.

AUTHORS
     The current piixpm driver was written by Alexander Yurchenko
     <grange@openbsd.org>.

BUGS
     The driver doesn't support I2C commands with a data buffer size of more
     than 2 bytes.
