From 89a22dadb8810983868f5bbbc5530b27bf714a60 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Mon, 4 Feb 2013 07:10:10 +0000 Subject: [PATCH] ACPI: enable ACPI SCI during suspend Enable ACPI SCI during suspend so that SCI can be used as wake events for PM_SUSPEND_FREEZE. For S3/S4 transition, We disable all GPEs in suspend_ops->prepare_late() to fix a problem that GPEs may trigger SCI before arch_suspend_disable_irqs() is run. So it is safe to leave the SCI enabled until arch_suspend_irq_disable() is run. Signed-off-by: Zhang Rui Signed-off-by: Rafael J.
