9  * The OMAP2 processor can be run at several discrete 'PRCM configurations'.
10  * These configurations are characterized by voltage and speed for clocks.
11  * The device is only validated for certain combinations. One way to express
12  * these combinations is via the 'ratios' which the clocks operate with
13  * respect to each other. These ratio sets are for a given voltage/DPLL
14  * setting. All configurations can be described by a DPLL setting and a ratio.
15  *
16  * 2430 differs from 2420 in that there are no more phase synchronizers used.
17  * They both have a slightly different clock domain setup. 2420(iva1,dsp) vs
18  * 2430 (iva2.1, NOdsp, mdm)
19  *
20  * XXX Missing voltage data.
21  * XXX Missing 19.2MHz sys_clk rate sets.
22  *
23  * THe format described in this file is deprecated.  Once a reasonable
24  * OPP API exists, the data in this file should be converted to use it.
25  *
26  * This is technically part of the OMAP2xxx clock code.

39  * Filling in table based on 2430-SDPs variants available.  There are
40  * quite a few more rate combinations which could be defined.
41  *
42  * When multiple values are defined the start up will try and choose
43  * the fastest one. If a 'fast' value is defined, then automatically,
44  * the /2 one should be included as it can be used.  Generally having
45  * more than one fast set does not make sense, as static timings need
46  * to be changed to change the set.  The exception is the bypass
47  * setting which is available for low power bypass.
48  *
49  * Note: This table needs to be sorted, fastest to slowest.
