In order to better facilitate the configuration of timing parameters
for device drivers, the default unit of frequency for communicating
with the power management functions is hertz (Hz) rather than
megahertz (MHz).
Should the application require MHz rather than Hz, the power
management service can be commanded to use MHz by passing the
new command
