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 prompt "Expose thermal sensors as hwmon device" 21 depends on HWMON=y || HWMON=THERMAL 22 default y 23 help 24 In case a sensor is registered with the thermal 25 framework, this option will also register it 26 as a hwmon. The sensor will then have the common 27 hwmon sysfs interface. 28 29 Say 'Y' here if you want all thermal sensors to 30 have hwmon sysfs interface too. 31 32config THERMAL_OF 33 bool 34 prompt "APIs to parse thermal data out of device tree" 35 depends on OF 36 default y 37 help 38 This options provides helpers to add the support to 39 read and parse thermal data definitions out of the 40 device tree blob. 41 42 Say 'Y' here if you need to build thermal infrastructure 43 based on device tree. 44 45choice 46 prompt "Default Thermal governor" 47 default THERMAL_DEFAULT_GOV_STEP_WISE 48 help 49 This option sets which thermal governor shall be loaded at 50 startup. If in doubt, select 'step_wise'. 51 52config THERMAL_DEFAULT_GOV_STEP_WISE 53 bool "step_wise" 54 select THERMAL_GOV_STEP_WISE 55 help 56 Use the step_wise governor as default. This throttles the 57 devices one step at a time. 58 59config THERMAL_DEFAULT_GOV_FAIR_SHARE 60 bool "fair_share" 61 select THERMAL_GOV_FAIR_SHARE 62 help 63 Use the fair_share governor as default. This throttles the 64 devices based on their 'contribution' to a zone. The 65 contribution should be provided through platform data. 66 67config THERMAL_DEFAULT_GOV_USER_SPACE 68 bool "user_space" 69 select THERMAL_GOV_USER_SPACE 70 help 71 Select this if you want to let the user space manage the 72 platform thermals. 73 74endchoice 75 76config THERMAL_GOV_FAIR_SHARE 77 bool "Fair-share thermal governor" 78 help 79 Enable this to manage platform thermals using fair-share governor. 80 81config THERMAL_GOV_STEP_WISE 82 bool "Step_wise thermal governor" 83 help 84 Enable this to manage platform thermals using a simple linear 85 governor. 86 87config THERMAL_GOV_USER_SPACE 88 bool "User_space thermal governor" 89 help 90 Enable this to let the user space manage the platform thermals. 91 92config CPU_THERMAL 93 bool "generic cpu cooling support" 94 depends on CPU_FREQ 95 depends on THERMAL_OF 96 help 97 This implements the generic cpu cooling mechanism through frequency 98 reduction. An ACPI version of this already exists 99 (drivers/acpi/processor_thermal.c). 100 This will be useful for platforms using the generic thermal interface 101 and not the ACPI interface. 102 103 If you want this support, you should say Y here. 104 105config THERMAL_EMULATION 106 bool "Thermal emulation mode support" 107 help 108 Enable this option to make a emul_temp sysfs node in thermal zone 109 directory to support temperature emulation. With emulation sysfs node, 110 user can manually input temperature and test the different trip 111 threshold behaviour for simulation purpose. 112 113 WARNING: Be careful while enabling this option on production systems, 114 because userland can easily disable the thermal policy by simply 115 flooding this sysfs node with low temperature values. 116 117config IMX_THERMAL 118 tristate "Temperature sensor driver for Freescale i.MX SoCs" 119 depends on CPU_THERMAL 120 depends on MFD_SYSCON 121 depends on OF 122 help 123 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs. 124 It supports one critical trip point and one passive trip point. The 125 cpufreq is used as the cooling device to throttle CPUs when the 126 passive trip is crossed. 127 128config SPEAR_THERMAL 129 bool "SPEAr thermal sensor driver" 130 depends on PLAT_SPEAR 131 depends on OF 132 help 133 Enable this to plug the SPEAr thermal sensor driver into the Linux 134 thermal framework. 135 136config RCAR_THERMAL 137 tristate "Renesas R-Car thermal driver" 138 depends on ARCH_SHMOBILE || COMPILE_TEST 139 help 140 Enable this to plug the R-Car thermal sensor driver into the Linux 141 thermal framework. 142 143config KIRKWOOD_THERMAL 144 tristate "Temperature sensor on Marvell Kirkwood SoCs" 145 depends on ARCH_KIRKWOOD 146 depends on OF 147 help 148 Support for the Kirkwood thermal sensor driver into the Linux thermal 149 framework.
