The documentation for the S3C6410 CPU voltage scaling is rather
unclear, with omitted values for several speed settings. Originally
the code was using only quoted values, resulting in some fairly odd
settings. The S3C6410 is also unusual in that the both the maximum
and minimum voltages quoted scale as the frequency rises, rather
than just the minimum voltage.
Clean this up a bit by always using the specified typical settings
as the minimum voltage (ignoring any specified minimum voltage) in
order to avoid running near the edge of the processor capabilities.
Also use the next quoted maximum voltages rather than the typical
voltages where no maximum voltage is quoted, allowing operation on
a greater range of systems.

Currently the transition latency reported by the S3C64xx cpufreq
driver includes both the time for the CPU to reclock itself and
the time for a regulator to change voltage. This means that if
a regulator is not in use then the transition latency reported
is excessively high.
In future the regulator API will be extended to report latencies
so the driver will be able to query the performance of a given
regulator.

DVDD is supplied by supplies derived from the PMIC, AVDD and PVDD are
supplied from the main wall supply on the base board which runs at
5V. No option is currently supported for running without a PMIC card,
the assumption is that the regulator API will be built out when no
soft PMIC card is in use.
To ease merge issues since this uses the newly added dev_name supply
configuration from the regulator API (currently in -next only) the
fixed voltage regulator is ifdefed out when the regulator API is not
enabled.

to make it easier to port new devices and try and clear up some of the
