+ * 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.

+ * 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.
