From 80b43a8b7cf535d2fdf7fdcb2606ca9fa3de526d Mon Sep 17 00:00:00 2001
From: Hersen Wu <hersenxs.wu@amd.com>
Date: Tue, 31 Oct 2017 15:55:15 -0400
Subject: [PATCH 2726/4131] drm/amd/display: send display_count msg so SMU can
enter S0i2
SMU can future lower voltages in long idle case when all display is off.
If all display output is turned off via DPMS, send display_count = 0
after all output are turned off.
otherwise send display_count msg before turning on display to make sure
SMU exit S0i2 state. before is not neccessary as we are out of S0i2
when driver execute code, but send message before anyways for correctness.
