   4 Subject: [PATCH] ARM: dts: overlays: Create custom clocks in /
   5
   6 Change [1] removes the simple-bus compatible string from the "/clocks"
   7 node, preventing any custom clocks placed there from being initialised.
   8 Rather than reinstate the compatible string and trigger DT warnings at
   9 kernel build time, change the overlays to instantiate those clocks under
  10 the root node ("/").
