It is just a warning message. I did more test today. I reverted it on my LX2160A with the SMMU-less config and rebooted. Then, I get this notification: dprc.1: DMA mask not set Still the DPRC binds, all DPAA2 children (dpni/dpio/dpbp) probe. In practice, it is more a cleanup warning/notification. I do not remember why I did state this commit log that is few month old. I'll rework the v2 per your suggested common block, I'll drop Cc: stable and update my commit log accordingly. Best regards, Vincent > Commit 4d8bde883bfb ("OF: Don't set default coherent DMA mask") is the > one that added the dev_warn.
