	bool "Power sequencing"
	depends on AP
	select HAS_TASK_CHIPSET
	help
	  Enable shimming the platform/ec AP power sequencing code. This
	  handles powering the chipset on and off.

	  Enabling this automatically enables HAS_TASK_CHIPSET since power
	  sequencing must run in its own task.

config PLATFORM_EC_POWERSEQ_HOST_SLEEP
	bool "Track host sleep states"
	help
	  Enable EC code to track the AP sleep states.  This is
	  required for S0ix support on Intel platforms, and optional
	  for boards without S0ix support.

menuconfig PLATFORM_EC_POWERSEQ_INTEL
	bool "Enable shimming common Intel power sequencing code"
	depends on AP_X86_INTEL
	default y
	help
	  Enable shimming platform/ec AP power sequencing code for
	  Intel.

config PLATFORM_EC_POWERSEQ_CPU_PROCHOT_ACTIVE_LOW
	bool "The CPU_PROCHOT signal is an active low signal"
	default y
	help
	  If CPU_PROCHOT should be treated as active-low, enable this
	  configuration option.

config PLATFORM_EC_POWERSEQ_PP5000_CONTROL
	bool "Enable a task-safe way to control the PP5000 rail"
	default y
	help
	  Guard access to the PP5000 GPIO using mutex locks, allowing
	  the rail to be changed in a task-safe manner.

config PLATFORM_EC_POWERSEQ_RSMRST_DELAY
	bool "Wait at least 10ms before deasserting RSMRST to PCH"
	default y if AP_X86_INTEL_TGL
	help
	  Wait at least 10ms between power signals going high and
	  deasserting RSMRST to PCH.

config PLATFORM_EC_POWERSEQ_RTC_RESET
	bool "Board has an RTC reset"
	help
	  This project has a gpio named GPIO_PCH_RTCRST defined in
	  gpio_map.h, which can be used to reset the AP's RTC when set
	  high.

config PLATFORM_EC_POWERSEQ_S0IX
	bool "Enable S0ix sleep states"
	select PLATFORM_EC_POWERSEQ_HOST_SLEEP
	help
	  Enable the CONFIG_POWER_S0IX platform/ec configuration
	  option, Intel's low-power idle sleep state, also known as
	  "modern sleep".

config PLATFORM_EC_POWERSEQ_COMETLAKE
	bool "Use common Comet Lake code for power sequencing"
	depends on AP_X86_INTEL_CML
	default y
	help
	  Use the Comet Lake code for power sequencing.

	bool "Use common Icelake code for power sequencing"
	default y if AP_X86_INTEL_TGL
	default y if AP_X86_INTEL_ADL
	help
	  Use the Icelake common code for power sequencing.  Note that
	  this applies to more platforms than just Icelake.  For
	  example, Tigerlake uses this code too.

	  Enable a quirk to reconfigure SLP_S3_L back to an input a
	  short delay after DSW_PWROK goes high.

config PLATFORM_EC_POWERSEQ_PP3300_RAIL_FIRST
	bool "Turn on the PP3300 rail before PP5000"
	default y if AP_X86_INTEL_TGL
	help
	  When switching from G3 to S5, turn on the PP3300 rail before
	  the PP5500 rail.
