+From: Phil Elwell <phil@raspberrypi.com>
+Date: Mon, 11 May 2020 15:12:21 +0100
+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
