Amit Daniel Kachhap e6e238c38b thermal: sysfs: Add a new sysfs node emul_temp for thermal emulation
This patch adds support to set the emulated temperature method in
thermal zone (sensor). After setting this feature thermal zone may
report this temperature and not the actual temperature. The emulation
implementation may be based on sensor capability through platform
specific handler or pure software emulation if no platform handler defined.

This is useful in debugging different temperature threshold and its
associated cooling action. Critical threshold's cannot be emulated.
Writing 0 on this node should disable emulation.

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.

prompt "Default Thermal governor"
default THERMAL_DEFAULT_GOV_STEP_WISE
help
This option sets which thermal governor shall be loaded at
startup. If in doubt, select 'step_wise'.
config THERMAL_DEFAULT_GOV_STEP_WISE
bool "step_wise"
select STEP_WISE
help
Use the step_wise governor as default. This throttles the
devices one step at a time.
config THERMAL_DEFAULT_GOV_FAIR_SHARE
bool "fair_share"
select FAIR_SHARE
help
Use the fair_share governor as default. This throttles the
devices based on their 'contribution' to a zone. The
contribution should be provided through platform data.
config THERMAL_DEFAULT_GOV_USER_SPACE
bool "user_space"
select USER_SPACE
help
Select this if you want to let the user space manage the
lpatform thermals.

config FAIR_SHARE
bool "Fair-share thermal governor"
help
Enable this to manage platform thermals using fair-share governor.
config STEP_WISE
bool "Step_wise thermal governor"
help
Enable this to manage platform thermals using a simple linear
config USER_SPACE
bool "User_space thermal governor"
help
Enable this to let the user space manage the platform thermals.
config CPU_THERMAL
tristate "generic cpu cooling support"
depends on CPU_FREQ
select CPU_FREQ_TABLE
help
This implements the generic cpu cooling mechanism through frequency
reduction, cpu hotplug and any other ways of reducing temperature. An
ACPI version of this already exists(drivers/acpi/processor_thermal.c).
This will be useful for platforms using the generic thermal interface
and not the ACPI interface.
If you want this support, you should say Y here.
config THERMAL_EMULATION
bool "Thermal emulation mode support"
help
Enable this option to make a emul_temp sysfs node in thermal zone
directory to support temperature emulation. With emulation sysfs node,
user can manually input temperature and test the different trip
threshold behaviour for simulation purpose.

Enable this to plug the SPEAr thermal sensor driver into the Linux
thermal framework

If you say yes here you get support for TMU (Thermal Management
Unit) on SAMSUNG EXYNOS series of SoC.

bool "EXYNOS TMU emulation mode support"
depends on EXYNOS_THERMAL
help
Exynos 4412 and 4414 and 5 series has emulation mode on TMU.
Enable this option will be make sysfs node in exynos thermal platform
device directory to support emulation mode. With emulation mode sysfs
node, you can manually input temperature to TMU for simulation purpose.

default y
help
Adds DB8500 thermal management implementation according to the thermal
management framework. A thermal zone with several trip points will be
created. Cooling devices can be bound to the trip points to cool this
thermal zone if trip points reached.

depends on CPU_THERMAL
default y
help
Adds DB8500 cpufreq cooling devices, and these cooling devices can be
bound to thermal zone trip points. When a trip point reached, the
bound cpufreq cooling device turns active to set CPU frequency low to
cool down the CPU.

Enable this to enable Intel PowerClamp idle injection driver. This
enforce idle time which results in more package C-state residency. The
user interface is exposed via generic thermal framework.
