piixpm* at pci?
iic* at piixpm?
piixpmdriver 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.
piixpmdriver 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.
piixpmdriver was written by Alexander Yurchenko <email@example.com>.
