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
Paul Walmsleyca6eccb2010-01-08 15:23:15 -070012 * these combinations is via the 'ratios' which the clocks operate with
Paul Walmsleyd8a94452009-12-08 16:21:29 -070013 * respect to each other. These ratio sets are for a given voltage/DPLL
Paul Walmsleyca6eccb2010-01-08 15:23:15 -070014 * setting. All configurations can be described by a DPLL setting and a ratio.
Paul Walmsleyd8a94452009-12-08 16:21:29 -070015 *
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.
Paul Walmsleyca6eccb2010-01-08 15:23:15 -070021 * XXX Missing 19.2MHz sys_clk rate sets.
Paul Walmsleyd8a94452009-12-08 16:21:29 -070022 *
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.

Paul Walmsleyca6eccb2010-01-08 15:23:15 -070042 * 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.
Paul Walmsleyd8a94452009-12-08 16:21:29 -070048 *
49 * Note: This table needs to be sorted, fastest to slowest.
