9 * The OMAP2 processor can be run at several discrete 'PRCM configurations'.
10 * These configurations are characterized by voltage and speed for clocks.
11 * The device is only validated for certain combinations. One way to express
12 * these combinations is via the 'ratios' which the clocks operate with
13 * respect to each other. These ratio sets are for a given voltage/DPLL
14 * setting. All configurations can be described by a DPLL setting and a ratio.
15 *
16 * XXX Missing voltage data.
17 * XXX Missing 19.2MHz sys_clk rate sets (needed for N800/N810)
18 *
19 * THe format described in this file is deprecated. Once a reasonable
20 * OPP API exists, the data in this file should be converted to use it.
21 *
22 * This is technically part of the OMAP2xxx clock code.
23 *
24 * Considerable work is still needed to fully support dynamic frequency
25 * changes on OMAP2xxx-series chips. Readers interested in such a
26 * project are encouraged to review the Maemo Diablo RX-34 and RX-44
