Subject: [PATCH AUTOSEL 5.5 22/58] drm/amd/display: Do not set optimized_require to false after plane disable
Date: Sat, 22 Feb 2020 21:20:43 -0500	[thread overview]
Message-ID: <20200223022119.707-22-sashal@kernel.org> (raw)
In-Reply-To: <20200223022119.707-1-sashal@kernel.org>

From: Sung Lee <sung.lee@amd.com>

[ Upstream commit df36f6cf23ada812930afa8ee76681d4ad307c61 ]

[WHY]
The optimized_require flag is needed to set watermarks and clocks lower
in certain conditions. This flag is set to true and then set to false
while programming front end in dcn20.

[HOW]
Do not set the flag to false while disabling plane.
