+Subject: [PATCH] dpaa_eth: defer probing after qbman
+
+Enabling SMMU altered the order of device probing causing the dpaa1
+ethernet driver to get probed before qbman and causing a boot crash.
+Add predictability in the probing order by deferring the ethernet
+driver probe after qbman and portals by using the recently introduced
+qbman APIs.
