Subject: [PATCH 512/678] 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.
|
|
