From 3d1b1ab4b483b95a97461bec4ee723356b367aae Mon Sep 17 00:00:00 2001
From: Fatemeh Darbehani <fatemeh.darbehani@amd.com>
Date: Fri, 5 Oct 2018 17:22:32 -0400
Subject: [PATCH 1134/2940] drm/amd/display: Retiring set_display_requirements
in dm_pp_smu.h - part4
[Why]
In DCN we want direct DC to SMU calls, with minimal interference from
pplib.
The reason for each pp_smu interface mapping to 1 SMU message is so we
can have the sequencing of different SMU message in DC and shared across
different OS's.
This will also simplify debugging as DAL owns this interaction and
there's no confusion about division of ownership.
[How]
Part 4: Change clock units so they match the values PPLib sends to SMU.
