+ * This driver is about to register JH7110 PLL clock generator and support ops.
+ * The JH7110 have three PLL clock, PLL0, PLL1 and PLL2.
+ * Each PLL clocks work in integer mode or fraction mode by some dividers,
+ * and the configuration registers and dividers are set in several syscon registers.
+ * The formula for calculating frequency is:
+ * Fvco = Fref * (NI + NF) / M / Q1
+ * Fref: OSC source clock rate
+ * NI: integer frequency dividing ratio of feedback divider, set by fbdiv[11:0].
+ * NF: fractional frequency dividing ratio, set by frac[23:0]. NF = frac[23:0] / 2^24 = 0 ~ 0.999.
+ * M: frequency dividing ratio of pre-divider, set by prediv[5:0].
+ * Q1: frequency dividing ratio of post divider, set by 2^postdiv1[1:0], eg. 1, 2, 4 or 8.
