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 | |
ca6eccb3 | 12 | * these combinations is via the 'ratios' which the clocks operate with |
d8a94458 | 13 | * respect to each other. These ratio sets are for a given voltage/DPLL |
ca6eccb3 | 14 | * setting. All configurations can be described by a DPLL setting and a ratio. |

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. | |
ca6eccb3 | 21 | * XXX Missing 19.2MHz sys_clk rate sets. |

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. | |

41 | * Filling in table based on 2430-SDPs variants available. There are |
42 | * quite a few more rate combinations which could be defined. | |

44 | * When multiple values are defined the start up will try and choose |
45 | * the fastest one. If a 'fast' value is defined, then automatically, | |
46 | * the /2 one should be included as it can be used. Generally having | |
47 | * more than one fast set does not make sense, as static timings need | |
48 | * to be changed to change the set. The exception is the bypass | |
49 | * setting which is available for low power bypass. | |

51 | * Note: This table needs to be sorted, fastest to slowest. | |
