From 74ad82d1beb22c28091571a377d8f5709655591b Mon Sep 17 00:00:00 2001
From: Michael Strauss <michael.strauss@amd.com>
Date: Mon, 4 Nov 2019 13:39:20 -0500
Subject: [PATCH 4669/4736] drm/amd/display: Fix Dali clk mgr construct
[WHY]
Dali is currently being misinterpreted as Renoir,
as a result uses wrong clk mgr constructor
[HOW]
Add check to init Dali as Raven2 before it can be misidentified
Clean up & fix Raven2 & Dali ASIC checks
