-Subject: [PATCH] overlays: Move "fixed-clock" nodes to the root
-
-Apart from some special cases, device objects are only created for
-nodes if they are children of a bus or the root node. "fixed-clock"
-is one of the exceptions that will be instantiated wherever it is
-found, but only during kernel initialisation - ruling out loading the
-overlay at runtime.
-
-Move most of the affected clocks to be children of the root, only
-leaving those in overlays that could be multiply instantiated, to avoid
-a potential name clash.
-
-See: https://github.com/raspberrypi/linux/issues/3602
