- Many Bay Trail and Cherry Trail devices come with a camera attached

+ The Intel Platform Controller Hub for Intel Core SoCs provides access

+ 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
