+Subject: [PATCH 200/203] BCM270X_DT: Make mmc overlay compatible with current
+ firmware
+
+The original DT overlay logic followed a merge-then-patch procedure,
+i.e. parameters are applied to the loaded overlay before the overlay
+is merged into the base DTB. This sequence has been changed to
+patch-then-merge, in order to support parameterised node names, and
+to protect against bad overlays. As a result, overrides (parameters)
+must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
+
+mmc-overlay.dts (that switches back to the original mmc sdcard
+driver) is the only overlay violating that rule, and this patch
+fixes it.
