If you say yes to this option, support will be included for the
Resource Power Manager system found in the Qualcomm 8974 based
devices.

This is required to access many regulators, clocks and bus
frequencies controlled by the RPM on these devices.

Say M here if you want to include support for the Qualcomm RPM as a
module. This will build a module called "qcom-smd-rpm".
