Subject: [PATCH AUTOSEL 4.14 09/21] ARM: dts: am4372: Set memory bandwidth limit for DISPC
Date: Wed, 9 Oct 2019 13:06:02 -0400 [thread overview]
Message-ID: <20191009170615.32750-9-sashal@kernel.org> (raw)
In-Reply-To: <20191009170615.32750-1-sashal@kernel.org>
From: Peter Ujfalusi <peter.ujfalusi@ti.com>
[ Upstream commit f90ec6cdf674248dcad85bf9af6e064bf472b841 ]
Set memory bandwidth limit to filter out resolutions above 720p@60Hz to
avoid underflow errors due to the bandwidth needs of higher resolutions.
am43xx can not provide enough bandwidth to DISPC to correctly handle
'high' resolutions.
