From 1a66f120abddf36eaf2540532ddeb7f7767442c5 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Sat, 1 Feb 2020 08:58:11 +0000 Subject: [PATCH] ARM: dts: Remove CMA allocation from Pi 4 dts The 5.5 tree includes a patch to disable the CMA command line parameter and replace it with properties from a DT node. The upstream Pi 4 .dts, now used downstream with modifications, includes the "linux,cma" node, but only reserves 32MB which is often not enough. Temporarily remove the "linux,cma" node to reenable the command line parameter.
