menuconfig THERMAL
	tristate "Generic Thermal sysfs driver"
	help
	  Generic Thermal Sysfs driver offers a generic mechanism for
	  thermal management. Usually it's made up of one or more thermal
	  zone and cooling device.
	  Each thermal zone contains its own temperature, trip points,
	  cooling devices.
	  All platforms with ACPI thermal support can use this driver.
	  If you want this support, you should say Y or M here.

if THERMAL

config THERMAL_STATISTICS
	bool "Thermal state transition statistics"
	help
	  Export thermal state transition statistics information through sysfs.

	  If in doubt, say N.

config THERMAL_EMERGENCY_POWEROFF_DELAY_MS
	int "Emergency poweroff delay in milli-seconds"
	depends on THERMAL
	default 0
	help
	  Thermal subsystem will issue a graceful shutdown when
	  critical temperatures are reached using orderly_poweroff(). In
	  case of failure of an orderly_poweroff(), the thermal emergency
	  poweroff kicks in after a delay has elapsed and shuts down the system.
	  This config is number of milliseconds to delay before emergency
	  poweroff kicks in. Similarly to the critical trip point,
	  the delay should be carefully profiled so as to give adequate
	  time for orderly_poweroff() to finish on regular execution.
	  If set to 0 emergency poweroff will not be supported.

	  In doubt, leave as 0.

	  This will throttle the device by limiting the maximum allowed DVFS
	  frequency corresponding to the cooling level.

	  In order to use the power extensions of the cooling device,
	  devfreq should use the simple_ondemand governor.
