Subject: [PATCH 19/49] drm/amd/display: clean up DML for DCN2x
Date: Fri, 9 Aug 2019 17:37:12 -0400	[thread overview]
Message-ID: <20190809213742.30301-20-sunpeng.li@amd.com> (raw)
In-Reply-To: <20190809213742.30301-1-sunpeng.li-5C7GfCeVMHo@public.gmane.org>

From: Jun Lei <Jun.Lei@amd.com>

[why]
Previous "less risky" implemenation of 3 tiered fallback is no longer necessary since
DMLv2 has gone through proper validation.  v2 can now be used as the default and 1
level of fallback can be removed

[how]
remove previous workaround implemenation
