 * 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:
