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

31    bool "step_wise"
32    select THERMAL_GOV_STEP_WISE
33    help
34      Use the step_wise governor as default. This throttles the
35      devices one step at a time.

38    bool "fair_share"
39    select THERMAL_GOV_FAIR_SHARE
40    help
41      Use the fair_share governor as default. This throttles the
42      devices based on their 'contribution' to a zone. The
43      contribution should be provided through platform data.

72    select CPU_FREQ_TABLE
73    help
74      This implements the generic cpu cooling mechanism through frequency
75      reduction, cpu hotplug and any other ways of reducing temperature. An
76      ACPI version of this already exists(drivers/acpi/processor_thermal.c).
77      This will be useful for platforms using the generic thermal interface
78      and not the ACPI interface.
79      If you want this support, you should say Y here.

81config THERMAL_EMULATION
82    bool "Thermal emulation mode support"
83    help
84      Enable this option to make a emul_temp sysfs node in thermal zone
85      directory to support temperature emulation. With emulation sysfs node,
86      user can manually input temperature and test the different trip
87      threshold behaviour for simulation purpose.

108    help
109      Support for the Kirkwood thermal sensor driver into the Linux thermal
110      framework. Only kirkwood 88F6282 and 88F6283 have this sensor.

124      Exynos 4412 and 4414 and 5 series has emulation mode on TMU.
125      Enable this option will be make sysfs node in exynos thermal platform
126      device directory to support emulation mode. With emulation mode sysfs
127      node, you can manually input temperature to TMU for simulation purpose.

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

151    default y
152    help
153      Adds DB8500 cpufreq cooling devices, and these cooling devices can be
154      bound to thermal zone trip points. When a trip point reached, the
155      bound cpufreq cooling device turns active to set CPU frequency low to
156      cool down the CPU.
