Author: marius Date: Sun Mar 22 10:08:41 2009 New Revision: 190256 URL: http://svn.freebsd.org/changeset/base/190256 Log: MFC: r182918 Add drivers for the power management devices found on Fireplane/ Safari- and JBus-based machines. Currently the main purpose of these drivers is debugging of the resource allocation on nexus(4) and the register content of these devices though.
