     13	  driver can utilize debugging capabilities and supported features as
     14	  exposed by the Power Management Controller. It also may perform some
     15	  tasks in the PMC in order to enable transition into the SLPS0 state.
     16	  It should be selected on all Intel platforms supported by the driver.
