0011 The Intel Platform Controller Hub for Intel Core SoCs provides access
0012 to Power Management Controller registers via various interfaces. This
0013 driver can utilize debugging capabilities and supported features as
0014 exposed by the Power Management Controller. It also may perform some
0015 tasks in the PMC in order to enable transition into the SLPS0 state.
0016 It should be selected on all Intel platforms supported by the driver.

0021 - LTR Ignore / LTR Show
0022 - MPHY/PLL gating status (Sunrisepoint PCH only)
0023 - SLPS0 Debug registers (Cannonlake/Icelake PCH)
0024 - Low Power Mode registers (Tigerlake and beyond)
0025 - PMC quirks as needed to enable SLPS0/S0ix
