+ * In the latter case, it will try to increase the presc value until

+ * calc_pll_params() and obtains the values of PD, MFI,MFN, MFD based
+ * on the targeted PLL and reference input clock to the PLL. Lastly,
+ * it sets the register based on these values along with the dividers.
+ * Note 1) There is no value checking for the passed-in divider values
+ *         so the caller has to make sure those values are sensible.
+ *      2) Also adjust the NFC divider such that the NFC clock doesn't
