+Subject: [PATCH] BCM270X_DT: Add non-removable clone of mmc node
+
+non-removable is a boolean property, and as such can't be unset by an
+overlay if it is set in a base DTB. Until now the workaround for this
+problem has been for overlays to clone non-removable nodes without
+the offending property, but this involves a lot of unnecessary
+replication. Instead, add a clone of the mmc node with non-removable
+already set to the base DTB, selecting the required version using
+the status properties.
