This contains startup and shutdown times for the oscillator. By default
use MAX_INT. Oscillator setup is used for calculating and setting up
latencies for sleep modes that disable oscillator.

As voltdm-pmic now contains startup and shutdown times for PMIC, use
these for calculating the fields in the PMICSETUPTIME register.

Voltage code will now enable / disable auto_ret / auto_off dynamically
according to the voltagedomain usecounts. This is accomplished via
the usage of the voltdm callback functions for sleep / wakeup.

If we are switching the state of an idle powerdomain, we must wait for
the wakeup to complete before attempting to switch to the new state,
otherwise the powerdomain may not be ready for the switch and will fail.

Hello,
Unfortunately the previous version of this work (SMPS regulator
was a separate driver) was rejected by the omap maintainers, thus
I am sending a new version. This implementation is going somewhat
back towards the original version, we are having an external
controller that replaces the
hardware.

VDD1 and VDD2 are the core voltage regulators on OMAP3. VDD1 is used
to control MPU/IVA voltage, and VDD2 is used for CORE. These regulators
are needed by DVFS.
