Huh? Why is this called "cpufreq" what is this the frequency of, exactly? Is this an input or an output? Cheers, Mark.
+- #clock-cells: Should be <1>.

+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/clps711x-clock.h
+for the full list of CLPS711X clock IDs.

+Example:
+ clks: clks at 80000000 {
+ #clock-cells = <1>;
+ compatible = "cirrus,ep7312-clk", "cirrus,clps711x-clk";
+ reg = <0x80000000 0xc000>;
+ cpufreq = <73728000>;
