- * @rate: target rate for the DPLL
- * @best_parent_rate: pointer for returning best parent rate
- * @best_parent_clk: pointer for returning best parent clock

  *
  * Determines which DPLL mode to use for reaching a desired rate.
  * Checks whether the DPLL shall be in bypass or locked mode, and if
  * locked, calculates the M,N values for the DPLL via round-rate.
- * Returns a positive clock rate with success, negative error value
- * in failure.
+ * Returns 0 on success and a negative error value otherwise.
