| 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. |
