+From f1ab2428459b22a026f8a6c1c83681fa8f725b98 Mon Sep 17 00:00:00 2001
+From: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com>
+Date: Mon, 24 Sep 2018 15:28:00 -0400
+Subject: [PATCH 0540/2940] drm/amd/display: split dccg clock manager into asic
+ folders
+
+Currently dccg contains code related to every dcn revision in
+a single file.
+
+This change splits out the dcn parts of code into correct folders
