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. 15 16if THERMAL 17 18config THERMAL_HWMON 19 bool 20 depends on HWMON=y || HWMON=THERMAL 21 default y 22 23choice 24 prompt "Default Thermal governor" 25 default THERMAL_DEFAULT_GOV_STEP_WISE 26 help 27 This option sets which thermal governor shall be loaded at 28 startup.

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. 80 81config SPEAR_THERMAL 82 bool "SPEAr thermal sensor driver" 83 depends on PLAT_SPEAR 84 depends on OF 85 help 86 Enable this to plug the SPEAr thermal sensor driver into the Linux 87 thermal framework 88 89config RCAR_THERMAL 90 tristate "Renesas R-Car thermal driver" 91 depends on ARCH_SHMOBILE 92 help 93 Enable this to plug the R-Car thermal sensor driver into the Linux 94 thermal framework 95 96config EXYNOS_THERMAL 97 tristate "Temperature sensor on Samsung EXYNOS" 98 depends on (ARCH_EXYNOS4 || ARCH_EXYNOS5) 99 depends on CPU_THERMAL 100 help 101 If you say yes here you get support for TMU (Thermal Management 102 Unit) on SAMSUNG EXYNOS series of SoC. 103 104config DB8500_THERMAL 105 bool "DB8500 thermal management" 106 depends on ARCH_U8500 107 default y 108 help 109 Adds DB8500 thermal management implementation according to the thermal 110 management framework. A thermal zone with several trip points will be 111 created.
