66 * The OMAP2 processor can be run at several discrete 'PRCM configurations'.
67 * These configurations are characterized by voltage and speed for clocks.
68 * The device is only validated for certain combinations. One way to express
69 * these combinations is via the 'ratio's' which the clocks operate with
70 * respect to each other. These ratio sets are for a given voltage/DPLL
71 * setting. All configurations can be described by a DPLL setting and a ratio
72 * There are 3 ratio sets for the 2430 and X ratio sets for 2420.
73 *
74 * 2430 differs from 2420 in that there are no more phase synchronizers used.
75 * They both have a slightly different clock domain setup. 2420(iva1,dsp) vs

339 * These represent optimal values for common parts, it won't work for all.
340 * As long as you scale down, most parameters are still work, they just
341 * become sub-optimal. The RFR value goes in the opposite direction. If you
342 * don't adjust it down as your clock period increases the refresh interval
343 * will not be met. Setting all parameters for complete worst case may work,
344 * but may cut memory performance by 2x. Due to errata the DLLs need to be
345 * unlocked and their value needs run time calibration. A dynamic call is
346 * need for that as no single right value exists acorss production samples.
347 *
348 * Only the FULL speed values are given. Current code is such that rate
349 * changes must be made at DPLLoutx2. The actual value adjustment for low
350 * frequency operation will be handled by omap_set_performance()
351 *
352 * By having the boot loader boot up in the fastest L4 speed available likely
353 * will result in something which you can switch between.
