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)
20 *
21 * XXX Missing voltage data.
22 * XXX Missing 19.2MHz sys_clk rate sets.
23 *
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.

27 * This is technically part of the OMAP2xxx clock code.

42 * Filling in table based on 2430-SDPs variants available. There are
43 * quite a few more rate combinations which could be defined.
44 *
45 * When multiple values are defined the start up will try and choose
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.
51 *
52 * Note: This table needs to be sorted, fastest to slowest.
