From d49747bdfb2ddebea24d1580da55b79d093d48a9 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Tue, 9 Oct 2007 12:37:13 -0500 Subject: powerpc/mpc83xx: Power Management support Basic PM support for 83xx. Standby is implemented as sleep. Suspend-to-RAM is implemented as "deep sleep" (with the processor turned off) on 831x.
