* 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 19.2MHz 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
* kernel source at:

*
* 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.
