12 The Intel Platform Controller Hub for Intel Core SoCs provides access
13 to Power Management Controller registers via various interfaces. This
14 driver can utilize debugging capabilities and supported features as
15 exposed by the Power Management Controller. It also may perform some
16 tasks in the PMC in order to enable transition into the SLPS0 state.
17 It should be selected on all Intel platforms supported by the driver.
20 - SLP_S0_RESIDENCY counter
21 - PCH IP Power Gating status
22 - LTR Ignore / LTR Show
23 - MPHY/PLL gating status (Sunrisepoint PCH only)
24 - SLPS0 Debug registers (Cannonlake/Icelake PCH)
25 - Low Power Mode registers (Tigerlake and beyond)
26 - PMC quirks as needed to enable SLPS0/S0ix
