From 3d7f1bfaf354ee371b90ba4e65463fcbd701feed Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Mon, 30 Sep 2019 11:54:50 +0300 Subject: [PATCH] ARM: dts: am4372: Set memory bandwidth limit for DISPC [ 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.
