|
|
* The OMAP2 processor can be run at several discrete 'PRCM configurations'.
|
|
* These configurations are characterized by voltage and speed for clocks.
|
|
* The device is only validated for certain combinations. One way to express
|
|
* these combinations is via the 'ratio's' which the clocks operate with
|
|
* respect to each other. These ratio sets are for a given voltage/DPLL
|
|
* setting. All configurations can be described by a DPLL setting and a ratio
|
|
* There are 3 ratio sets for the 2430 and X ratio sets for 2420.
|
|
*
|
|
* 2430 differs from 2420 in that there are no more phase synchronizers used.
|
|
* They both have a slightly different clock domain setup. 2420(iva1,dsp) vs
|
|
* 2430 (iva2.1, NOdsp, mdm)
|
|
*
|
|
* XXX Missing voltage data.
|
|
*
|
|
* THe format described in this file is deprecated. Once a reasonable
|
|
* OPP API exists, the data in this file should be converted to use it.
|
|
*
|
|
* This is technically part of the OMAP2xxx clock code.

|
|
* There are quite a few more rates combinations which could be defined.
|
|
*
|
|
* When multiple values are defined the start up will try and choose the
|
|
* fastest one. If a 'fast' value is defined, then automatically, the /2
|
|
* one should be included as it can be used. Generally having more that
|
|
* one fast set does not make sense, as static timings need to be changed
|
|
* to change the set. The exception is the bypass setting which is
|
|
* availble for low power bypass.
|
|
*
|
|
* Note: This table needs to be sorted, fastest to slowest.
