The SI unit of frequency is Hertz, named after Heinrich Hertz, and is given the symbol "Hz" to denote this. "hz" is not the unit of frequency, and is in fact meaningless. Fix arch/arm to correctly use "Hz", thereby acknowledging Heinrich Hertz' contribution to the modern world.

|
|
* The OMAP2 processor can be run at several discrete 'PRCM configurations'.
|
|
* These configurations are characterized by voltage and speed for clocks.
|
|
* The device is only validated for certain combinations. One way to express
|
|
* these combinations is via the 'ratios' which the clocks operate with
|
|
* respect to each other. These ratio sets are for a given voltage/DPLL
|
|
* setting. All configurations can be described by a DPLL setting and a ratio.
|
|
*
|
|
* 2430 differs from 2420 in that there are no more phase synchronizers used.
|
|
* They both have a slightly different clock domain setup. 2420(iva1,dsp) vs
|
|
* 2430 (iva2.1, NOdsp, mdm)
|
|
*
|
|
* XXX Missing voltage data.
|
|
* XXX Missing 19.2MHz sys_clk rate sets.
|
|
*
|
|
* THe format described in this file is deprecated. Once a reasonable
|
|
* OPP API exists, the data in this file should be converted to use it.
|
|
*
|
|
* This is technically part of the OMAP2xxx clock code.

|
|
* quite a few more rate combinations which could be defined.
|
|
*
|
|
* When multiple values are defined the start up will try and choose
|
|
* the fastest one. If a 'fast' value is defined, then automatically,
|
|
* the /2 one should be included as it can be used. Generally having
|
|
* more than one fast set does not make sense, as static timings need
|
|
* to be changed to change the set. The exception is the bypass
|
|
* setting which is available for low power bypass.

|

* Note: This table needs to be sorted, fastest to slowest.
