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