From f517709d65beed95f52f021b43e3035b52ef791a Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 17 Feb 2010 23:41:49 +0100 Subject: ACPI / PM: Add more run-time wake-up fields Use the run_wake flag to mark all devices for which run-time wake-up events may be generated by the platform. Introduce a new wake-up flag, always_enabled, for marking devices that should be permanently enabled to generate run-time events. Also, introduce a reference counter for run-wake devices and a function that will initialize all of the run-time wake-up fields for given device. Signed-off-by: Rafael J.
