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) | ||

24 | * OPP API exists, the data in this file should be converted to use it. | ||

39 | * Filling in table based on H4 boards and 2430-SDPs variants available. | ||
40 | * There are quite a few more rates combinations which could be defined. | ||
41 | * | ||
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. | ||
