+ * anpu_pll_set_rate() - API for smc function to set rate of voltage domain.
+ * @domain: Which pll of correspond voltage domain to change rate.
+ * @mode: which mode to use when set_rate
+ * @freq: which frequency to set.
+ *
+ * For V_VPU0/1, it will only allow 1 of them to modify NPUPLL
+ * such that there will be no race condition happen.
+ *
+ * For V_MDLA0/1, it will only allow 1 of them to modify APUPLL1
+ * such that there will be no race condition happen.
+ *
+ * There are 3 kinds of modes to set pll's rate.
+ * 1. pure sw mode: (CON0_PCW)
+ *        fhctl function is off and change rate by programming CON1_PCW.
+ * 2. fhctl sw mode: (FHCTL_SW)
+ *        fhctl function is on and change rate by programming fhctl_dds.
+ *        (post dividor is still need to program CON1_PCW)
+ * 3. fhctl hw mode: (FHCTL_HW)
+ *        fhctl function is on and change rate by programming fhctl_dvfs.
+ *        (post dividor is still need to program CON1_PCW)
+ *
+ * Context: Any context.
+ * Return:
