+ *
+ * This is a helper function designed for timers which need to fall back on the
+ * cpu's timebase. This function is designed to be called during the driver's
+ * probe(). If there is a clocks or clock-frequency property in the timer's
+ * binding, then it will be used. Otherwise, the timebase of the current cpu
+ * will be used. This is initialized by the cpu driver, and usually gotten from
+ * ``/cpus/timebase-frequency`` or ``/cpus/cpu@X/timebase-frequency``.
+ *
+ * Return: 0 if OK, or negative error code on failure
