From 5d30bf309717a518d0c4180af41650d4dcd3bb38 Mon Sep 17 00:00:00 2001 From: Manish Ahuja Date: Thu, 8 Feb 2007 16:01:17 -0600 Subject: [POWERPC] pseries: Enabling auto poweron after power is restored. During power outages, the UPS notifies the system for a shutdown. In the current setup, it isn't possible to poweron when power is restored. This patch fixes the issue by calling the right ibm,power-off-ups token during such events. It also adds a sysfs interface so userspace can specify whether or not to power on when power is restored.
