| 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 "Expose thermal sensors as hwmon device" |
| depends on HWMON=y || HWMON=THERMAL |
| default y |
| help |
| In case a sensor is registered with the thermal |
| framework, this option will also register it |
| as a hwmon. The sensor will then have the common |
| hwmon sysfs interface. |
| |
| Say 'Y' here if you want all thermal sensors to |
| have hwmon sysfs interface too. |

| config THERMAL_OF |
| bool |
| prompt "APIs to parse thermal data out of device tree" |
| depends on OF |
| default y |
| help |
| This options provides helpers to add the support to |
| read and parse thermal data definitions out of the |
| device tree blob. |
| |
| Say 'Y' here if you need to build thermal infrastructure |
| based on device tree. |
| |
| config THERMAL_WRITABLE_TRIPS |
| bool "Enable writable trip points" |
| help |
| This option allows the system integrator to choose whether |
| trip temperatures can be changed from userspace. The |
| writable trips need to be specified when setting up the |
| thermal zone but the choice here takes precedence. |
| |
| Say 'Y' here if you would like to allow userspace tools to |
| change trip temperatures. |

| 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 THERMAL_GOV_FAIR_SHARE |
| help |
| Use the fair_share governor as default. This throttles the |

| help |
| Enable this to manage platform thermals using bang bang governor. |
| |
| Say 'Y' here if you want to use two point temperature regulation |
| used for fans without throttling. Some fan drivers depend on this |
| governor to be enabled (e.g. acerhdf). |

| config CPU_THERMAL |
| bool "generic cpu cooling support" |
| depends on CPU_FREQ |
| depends on THERMAL_OF |
| help |
| This implements the generic cpu cooling mechanism through frequency |
| reduction. 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 CLOCK_THERMAL |
| bool "Generic clock cooling support" |
| depends on COMMON_CLK |
| depends on PM_OPP |
| help |
| This entry implements the generic clock cooling mechanism through |
| frequency clipping. Typically used to cool off co-processors. The |
| device that is configured to use this cooling mechanism will be |
| controlled to reduce clock frequency whenever temperature is high. |
| |
| config DEVFREQ_THERMAL |
| bool "Generic device cooling support" |
| depends on PM_DEVFREQ |
| depends on PM_OPP |
| help |
| This implements the generic devfreq cooling mechanism through |
| frequency reduction for devices using devfreq. |
| |
| 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. |
| |
| 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. |
| |
| WARNING: Be careful while enabling this option on production systems, |
| because userland can easily disable the thermal policy by simply |
| flooding this sysfs node with low temperature values. |
