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.

An ACPI version of this already exists 109 (drivers/acpi/processor_thermal.c). 110 This will be useful for platforms using the generic thermal interface 111 and not the ACPI interface. 112 113 If you want this support, you should say Y here. 114 115config CLOCK_THERMAL 116 bool "Generic clock cooling support" 117 depends on COMMON_CLK 118 depends on PM_OPP 119 help 120 This entry implements the generic clock cooling mechanism through 121 frequency clipping. Typically used to cool off co-processors. The 122 device that is configured to use this cooling mechanism will be 123 controlled to reduce clock frequency whenever temperature is high. 124 125 If you want this support, you should say Y here. 126 127config THERMAL_EMULATION 128 bool "Thermal emulation mode support" 129 help 130 Enable this option to make a emul_temp sysfs node in thermal zone 131 directory to support temperature emulation. With emulation sysfs node, 132 user can manually input temperature and test the different trip 133 threshold behaviour for simulation purpose. 134 135 WARNING: Be careful while enabling this option on production systems, 136 because userland can easily disable the thermal policy by simply 137 flooding this sysfs node with low temperature values. 138 139config IMX_THERMAL 140 tristate "Temperature sensor driver for Freescale i.MX SoCs" 141 depends on CPU_THERMAL 142 depends on MFD_SYSCON 143 depends on OF 144 help 145 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs. 146 It supports one critical trip point and one passive trip point.

The driver supports four thermal zones 216 (CPU, GPU, MEM, PLLX). Cooling devices can be bound to the thermal 217 zones to manage temperatures. This option is also required for the 218 emergency thermal reset (thermtrip) feature to function. 219 220config DB8500_CPUFREQ_COOLING 221 tristate "DB8500 cpufreq cooling" 222 depends on ARCH_U8500 223 depends on CPU_THERMAL 224 default y 225 help 226 Adds DB8500 cpufreq cooling devices, and these cooling devices can be 227 bound to thermal zone trip points.
