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
Paul Walmsleyca6eccb2010-01-08 15:23:15 -070012 * these combinations is via the 'ratios' which the clocks operate with
Paul Walmsleyd8a94452009-12-08 16:21:29 -070013 * respect to each other. These ratio sets are for a given voltage/DPLL
Paul Walmsleyca6eccb2010-01-08 15:23:15 -070014 * setting. All configurations can be described by a DPLL setting and a ratio.

16 * XXX Missing voltage data.
Paul Walmsleyca6eccb2010-01-08 15:23:15 -070017 * XXX Missing 19.2MHz sys_clk rate sets (needed for N800/N810)

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.
Paul Walmsleyca6eccb2010-01-08 15:23:15 -070023 *
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
27 * kernel source at:

Paul Walmsleyca6eccb2010-01-08 15:23:15 -070046 * When multiple values are defined the start up will try and choose
47 * the fastest one. If a 'fast' value is defined, then automatically,
48 * the /2 one should be included as it can be used. Generally having
49 * more than one fast set does not make sense, as static timings need
50 * to be changed to change the set. The exception is the bypass
51 * setting which is available for low power bypass.
