    v4 -> v5:
       - Add Reviewed-by: Rob Herring <robh@...nel.org>.
    v3 -> v4:
       - Fix node name to clock-controller.
       - Remove osc2-clk-frequency, and this defines to DT as
         fixed-clock.
       - Add clocks.
    v2 -> v3:
       - Change file name.
    v1 -> v2:
       - Update subject.
