| 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. |

| help |
| This options provides helpers to add the support to |

| 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. |

| 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. |

| bool "Generic clock cooling support" |
| depends on COMMON_CLK |
| depends on PM_OPP |
| help |
| This entry implements the generic clock cooling mechanism through |

| 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. |
