thermal: introduce device tree parser This patch introduces a device tree bindings for describing the hardware thermal behavior and limits. Also a parser to read and interpret the data and feed it in the thermal framework is presented. This patch introduces a thermal data parser for device tree. The parsed data is used to build thermal zones and thermal binding parameters. The output data can then be used to deploy thermal policies. This patch adds also documentation regarding this API and how to define tree nodes to use this infrastructure. Note that, in order to be able to have control on the sensor registration on the DT thermal zone, it was required to allow changing the thermal zone .get_temp callback. For this reason, this patch also removes the 'const' modifier from the .ops field of thermal zone devices.

thermal: introduce the Power Allocator governor The power allocator governor is a thermal governor that controls system and device power allocation to control temperature. Conceptually, the implementation divides the sustainable power of a thermal zone among all the heat sources in that zone. This governor relies on "power actors", entities that represent heat sources. They can report current and maximum power consumption and can set a given maximum power consumption, usually via a cooling device. The governor uses a Proportional Integral Derivative (PID) controller driven by the temperature of the thermal zone. The output of the controller is a power budget that is then allocated to each power actor that can have bearing on the temperature we are trying to control. It decides how much power to give each cooling device based on the performance they are requesting. The PID controller ensures that the total power budget does not exceed the control temperature.

It is intended to control fans, which can not be throttled but just switched on or off. Bang-bang cannot be set as default governor as it is intended for special devices only.

thermal: introduce clock cooling device This patch introduces a new thermal cooling device based on common clock framework. The original motivation to write this cooling device is to be able to cool down thermal zones using clocks that feed co-processors, such as GPUs, DSPs, Image Processing Co-processors, etc. But it is written in a way that it can be used on top of any clock. The implementation is pretty straight forward. The code creates a thermal cooling device based on a pair of a struct device and a clock name. The struct device is assumed to be usable by the OPP layer. The OPP layer is used as source of the list of possible frequencies. The (cpufreq) frequency table is then used as a map from frequencies to cooling states. Cooling states are indexes to the frequency table. The logic sits on top of common clock framework, specifically on clock pre notifications. Any PRE_RATE_CHANGE is hijacked, and the transition is only allowed when the new rate is within the thermal limit (cooling state -> freq). When a thermal cooling device state transition is requested, the clock is also checked to verify if the current clock rate is within the new thermal limit.

After setting this feature thermal zone may report this temperature and not the actual temperature. The emulation implementation may be based on sensor capability through platform specific handler or pure software emulation if no platform handler defined. This is useful in debugging different temperature threshold and its associated cooling action. Critical threshold's cannot be emulated. Writing 0 on this node should disable emulation.

thermal: add imx thermal driver support This is based on the initial imx thermal work done by Rob Lee <rob.lee@linaro.org> (Not sure if the email address is still valid). Since he is no longer interested in the work and I have rewritten a significant amount of the code, I just took the authorship over from him. It adds the imx thermal support using Temperature Monitor (TEMPMON) block found on some Freescale i.MX SoCs. The driver uses syscon regmap interface to access TEMPMON control registers and calibration data, and supports cpufreq as the cooling device.

thermal: Intel SoC DTS thermal In the Intel SoCs like Bay Trail, there are 2 additional digital temperature sensors(DTS), in addition to the standard DTSs in the core. Also they support 4 programmable thresholds, out of which two can be used by OSPM. These thresholds can be used by OSPM thermal control. Out of these two thresholds, one is used by driver and one user mode can change via thermal sysfs to get notifications on threshold violations. The driver defines one critical trip points, which is set to TJ MAX - offset. The offset can be changed via module parameter (default 5C). Also it uses one of the thresholds to get notification for this temperature violation. This is very important for orderly shutdown as the many of these devices don't have ACPI thermal zone, and expects that there is some other thermal control mechanism present in OSPM. When a Linux distro is used without additional specialized thermal control program, BIOS can do force shutdown when thermals are not under control. When temperature reaches critical, the Linux thermal core will initiate an orderly shutdown.

thermal: intel Quark SoC X1000 DTS thermal driver In Intel Quark SoC X1000, there is one on-die digital temperature sensor(DTS). The DTS offers both hot & critical trip points. However, in current distribution of UEFI BIOS for Quark platform, only critical trip point is configured to be 105 degree Celsius (based on Quark SW ver1.0.1 and hot trip point is not used due to lack of IRQ. There is no active cooling device for Quark SoC, so Quark SoC thermal management logic expects Linux distro to orderly power-off when temperature of the DTS exceeds the configured critical trip point. Kernel param "polling_delay" in milliseconds is used to control the frequency the DTS temperature is read by thermal framework. It defaults to 2-second. To change it, use kernel boot param "intel_quark_dts_thermal.polling_delay=X". User interacts with Quark SoC DTS thermal driver through sysfs via: /sys/class/thermal/thermal_zone0/ For example: - to read DTS temperature $ cat temp - to read critical trip point $ cat trip_point_0_temp - to read trip point type $ cat trip_point_0_type - to emulate temperature raise to test orderly shutdown by Linux distro $ echo 105 > emul_temp Tested-by: Bryan O'Donoghue <pure.logic@nexus-software.ie> Signed-off-by: Ong Boon Leong <boon.leong.ong@intel.com> Reviewed-by: Bryan O'Donoghue <pure.logic@nexus-software.ie> Reviewed-by: Kweh, Hock Leong <hock.leong.kweh@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

thermal: Add QPNP PMIC temperature alarm driver Add support for the temperature alarm peripheral found inside Qualcomm plug-and-play (QPNP) PMIC chips. The temperature alarm peripheral outputs a pulse on an interrupt line whenever the thermal over temperature stage value changes. Register a thermal sensor. The temperature reported by this thermal sensor device should reflect the actual PMIC die temperature if an ADC is present on the given PMIC. If no ADC is present, then the reported temperature should be estimated from the over temperature stage value. Cc: David Collins <collinsd@codeaurora.org> Signed-off-by: Ivan T.

Revert "thermal: qcom_spmi: allow compile test" This just caused build errors: warning: (QCOM_SPMI_TEMP_ALARM) selects REGMAP_SPMI which has unmet direct dependencies (SPMI) drivers/built-in.o: In function `regmap_spmi_ext_gather_write': :(.text+0x609b0): undefined reference to `spmi_ext_register_write' :(.text+0x609f0): undefined reference to `spmi_ext_register_writel' While it's generally a good idea to allow compile testing, in this case, it just doesn't work, so reverting the patch that introduced the compile-test variant seems the most appropriate solution. Note that SPMI also has a 'depends on ARCH_QCOM || COMPILE_TEST' statement, so we should be able to enable SPMI on all architectures for compile testing already.
