There are two type of devices:
A.) With fixed performance state requirements and they will have the
new "required-opp" property in the device node itself as you said.
B.) Devices which can do DVFS (CPU, MMC, LCD, etc) and those may need
a different performance state of the domain for their individual OPPs
and so we can't have this property in the device all the time.
Does this make sense ?
