67 * The OMAP2 processor can be run at several discrete 'PRCM configurations'.

69 * The device is only validated for certain combinations. One way to express
70 * these combinations is via the 'ratio's' which the clocks operate with
71 * respect to each other. These ratio sets are for a given voltage/DPLL
72 * setting. All configurations can be described by a DPLL setting and a ratio
73 * There are 3 ratio sets for the 2430 and X ratio sets for 2420.

75 * 2430 differs from 2420 in that there are no more phase synchronizers used.
76 * They both have a slightly different clock domain setup. 2420(iva1,dsp) vs
