Request
Response
RegisterPowerDomain
Register the callee for this power domain. The callee will be registered until
UnregisterPowerDomain is called. Any voltage changes to the power domain will
be made considering the min_needed_voltage(in uV) and max_supported_voltage(in uV) published here.
If voltages mentioned are out of supported voltage range of domain(obtained by calling
GetSupportedVoltageRange), the callee will be registered with the supported voltage range.

Response
RequestVoltage
Request a particular voltage. The actual_voltage is the voltage that the power domain
is transitioned to after considering supported voltage ranges of all the registered
dependents. "voltage" should be in uV.
