From 7a1a8eb58a2c6cd819d17332c5a2c369203635d5 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 3 Dec 2009 21:19:18 +0100 Subject: PM: Add flag for devices capable of generating run-time wake-up events Apparently, there are devices that can wake up the system from sleep states and yet are incapable of generating wake-up events at run time. Thus, introduce a flag indicating if given device is capable of generating run-time wake-up events. Signed-off-by: Rafael J.
