From 0fe1d4b9fe56a0f27a6ff39cfb94d63559b729b8 Mon Sep 17 00:00:00 2001
From: Nicholas Chin <nic.c3.14@gmail.com>

Subject: [PATCH 66/67] mb/dell: Add S3 SMI handler for Dell Latitudes
Integrate the previously added mec5035_smi_sleep() function into
mainboard code to fix S3 suspend on the SNB/IVB Latitudes and the E7240.
The E6400 does not require the EC command to sucessfully suspend and
resume from S3, though sending it does enable the breathing effect on
the power LED while in S3. Without it, all LEDs turn off during S3.
