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

41  * Filling in table based on H4 boards available.  There are quite a
42  * few more rate combinations which could be defined.
43  *
44  * When multiple values are defined the start up will try and choose
45  * the fastest one. If a 'fast' value is defined, then automatically,
46  * the /2 one should be included as it can be used.  Generally having
47  * more than one fast set does not make sense, as static timings need
48  * to be changed to change the set.  The exception is the bypass
49  * setting which is available for low power bypass.
50  *
51  * Note: This table needs to be sorted, fastest to slowest.
