* The OMAP2 processor can be run at several discrete 'PRCM configurations'.
* These configurations are characterized by voltage and speed for clocks.
* The device is only validated for certain combinations. One way to express
* these combinations is via the 'ratio's' which the clocks operate with
* respect to each other. These ratio sets are for a given voltage/DPLL
* setting. All configurations can be described by a DPLL setting and a ratio
* There are 3 ratio sets for the 2430 and X ratio sets for 2420.
*
* 2430 differs from 2420 in that there are no more phase synchronizers used.
* They both have a slightly different clock domain setup. 2420(iva1,dsp) vs
* 2430 (iva2.1, NOdsp, mdm)
*
* XXX Missing voltage data.
*
* THe format described in this file is deprecated. Once a reasonable
* OPP API exists, the data in this file should be converted to use it.
*
* This is technically part of the OMAP2xxx clock code.
