4 Subject: [PATCH] overlays: Move "fixed-clock" nodes to the root
5
6 Apart from some special cases, device objects are only created for
7 nodes if they are children of a bus or the root node. "fixed-clock"
8 is one of the exceptions that will be instantiated wherever it is
9 found, but only during kernel initialisation - ruling out loading the
10 overlay at runtime.
11
12 Move most of the affected clocks to be children of the root, only
13 leaving those in overlays that could be multiply instantiated, to avoid
14 a potential name clash.
