 *
 * 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 'ratios' 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.
 *
 * 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.
 * XXX Missing 19.2MHz sys_clk rate sets.
 *
 * 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.

 * Key dividers which make up a PRCM set. Ratios for a PRCM are mandated.
 * xtal_speed, dpll_speed, mpu_speed, CM_CLKSEL_MPU,
 * CM_CLKSEL_DSP, CM_CLKSEL_GFX, CM_CLKSEL1_CORE, CM_CLKSEL1_PLL,
 * CM_CLKSEL2_PLL, CM_CLKSEL_MDM
 *
 * Filling in table based on 2430-SDPs variants available.  There are
 * quite a few more rate combinations which could be defined.
 *
 * When multiple values are defined the start up will try and choose
 * the fastest one. If a 'fast' value is defined, then automatically,
 * the /2 one should be included as it can be used.  Generally having
 * more than one fast set does not make sense, as static timings need
 * to be changed to change the set.  The exception is the bypass
 * setting which is available for low power bypass.
 *
 * Note: This table needs to be sorted, fastest to slowest.
