60 * The OMAP2 processor can be run at several discrete 'PRCM configurations'.

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

2482 * This clock is a composite clock which does entire set changes then

2484 * be any key speed part of a set in the rate table.
2485 *
2486 * to really change a set, you need memory table sets which get changed
2487 * in sram, pre-notifiers & post notifiers, changing the top set, without
2488 * having low level display recalc's won't work... this is why dpm notifiers
2489 * work, isr's off, walk a list of clocks already _off_ and not messing with
2490 * the bus.
2491 *
2492 * This clock should have no parent. It embodies the entire upper level
2493 * active set. A parent will mess up some of the init also.
