  10  * The OMAP2 processor can be run at several discrete 'PRCM configurations'.
  11  * These configurations are characterized by voltage and speed for clocks.
  12  * The device is only validated for certain combinations. One way to express
  13  * these combinations is via the 'ratios' which the clocks operate with
  14  * respect to each other. These ratio sets are for a given voltage/DPLL
  15  * setting. All configurations can be described by a DPLL setting and a ratio.
  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)

  21  * XXX Missing voltage data.

  24  * THe format described in this file is deprecated.  Once a reasonable
  25  * OPP API exists, the data in this file should be converted to use it.

  46  * the fastest one. If a 'fast' value is defined, then automatically,
  47  * the /2 one should be included as it can be used.  Generally having
  48  * more than one fast set does not make sense, as static timings need
  49  * to be changed to change the set.  The exception is the bypass
  50  * setting which is available for low power bypass.
