|
|
* 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 'ratios' 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.
|
|
*
|
|
* 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.
|
|
* XXX Missing 19.2MHz sys_clk rate sets.
|
|
*
|
|
* 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.

* Filling in table based on 2430-SDPs variants available. There are
|
|
* quite a few more rate 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 than 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 available for low power bypass.
|
|
*
|
|
* Note: This table needs to be sorted, fastest to slowest.
