9  * The OMAP2 processor can be run at several discrete 'PRCM configurations'.
10  * These configurations are characterized by voltage and speed for clocks.
11  * The device is only validated for certain combinations. One way to express
12  * these combinations is via the 'ratio's' which the clocks operate with
13  * respect to each other. These ratio sets are for a given voltage/DPLL
14  * setting. All configurations can be described by a DPLL setting and a ratio
15  * There are 3 ratio sets for the 2430 and X ratio sets for 2420.
16  *
17  * 2430 differs from 2420 in that there are no more phase synchronizers used.
18  * They both have a slightly different clock domain setup. 2420(iva1,dsp) vs
19  * 2430 (iva2.1, NOdsp, mdm)

42  * When multiple values are defined the start up will try and choose the
43  * fastest one. If a 'fast' value is defined, then automatically, the /2
44  * one should be included as it can be used.    Generally having more that
45  * one fast set does not make sense, as static timings need to be changed
46  * to change the set.    The exception is the bypass setting which is
47  * availble for low power bypass.
