-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.
