| 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. |

| config CPU_THERMAL |
| bool "generic cpu cooling support" |
| depends on CPU_FREQ |
| 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 |

| 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. |

| to set threshold temperature for both warm and cool and update |
| thermal userspace client when a threshold is reached. Warm/Cool |
| temperature thresholds can be set independently for each sensor. |

| help |
| This enables thermal monitoring capability in the kernel in the |
| absence of a system wide thermal monitoring entity or until such an |
| entity starts running in the userspace. Monitors TSENS temperature |
| and limits the max frequency of the cores. |

| help |
| This enables a thermal Sysfs driver for Qualcomm plug-and-play (QPNP) |
| PMIC devices. It shows up in Sysfs as a thermal zone with multiple |
| trip points. The temperature reported by the thermal zone reflects the |
| real time die temperature if an ADC is present or an estimate of the |
| temperature based upon the over temperature stage value if no ADC is |
| available. If allowed via compile time configuration; enabling the |
| thermal zone device via the mode file results in shifting PMIC over |
| temperature shutdown control from hardware to software. |
