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. |
