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.

This throttles the 42 devices based on their 'contribution' to a zone. The 43 contribution should be provided through platform data. 44 45config THERMAL_DEFAULT_GOV_USER_SPACE 46 bool "user_space" 47 select THERMAL_GOV_USER_SPACE 48 help 49 Select this if you want to let the user space manage the 50 lpatform thermals. 51 52endchoice 53 54config THERMAL_GOV_FAIR_SHARE 55 bool "Fair-share thermal governor" 56 help 57 Enable this to manage platform thermals using fair-share governor. 58 59config THERMAL_GOV_STEP_WISE 60 bool "Step_wise thermal governor" 61 help 62 Enable this to manage platform thermals using a simple linear 63 64config THERMAL_GOV_USER_SPACE 65 bool "User_space thermal governor" 66 help 67 Enable this to let the user space manage the platform thermals. 68 69config CPU_THERMAL 70 tristate "generic cpu cooling support" 71 depends on CPU_FREQ 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. 80 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. 88 89config SPEAR_THERMAL 90 bool "SPEAr thermal sensor driver" 91 depends on PLAT_SPEAR 92 depends on OF 93 help 94 Enable this to plug the SPEAr thermal sensor driver into the Linux 95 thermal framework 96 97config RCAR_THERMAL 98 tristate "Renesas R-Car thermal driver" 99 depends on ARCH_SHMOBILE 100 help 101 Enable this to plug the R-Car thermal sensor driver into the Linux 102 thermal framework 103 104config KIRKWOOD_THERMAL 105 tristate "Temperature sensor on Marvell Kirkwood SoCs" 106 depends on ARCH_KIRKWOOD 107 depends on OF 108 help 109 Support for the Kirkwood thermal sensor driver into the Linux thermal 110 framework.
