* 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 .
*
* XXX Missing voltage data .
* XXX Missing 19 . 2 MHz sys_clk rate sets ( needed for N800 / N810 )
*
* 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 .
*
* Considerable work is still needed to fully support dynamic frequency
* changes on OMAP2xxx - series chips . Readers interested in such a
* project are encouraged to review the Maemo Diablo RX - 34 and RX - 44

* Key dividers which make up a PRCM set . Ratios for a PRCM are mandated .

* CM_CLKSEL2_PLL , CM_CLKSEL_MDM
*
* Filling in table based on H4 boards 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 .
