This work includes the introduction of a device tree bindings for describing the hardware thermal behavior and limits, and also a parser to read and interpret the data, and build thermal zones and thermal binding parameters. It also contains three examples on how to use the new representation on sensor devices, using three different drivers to accomplish it. One driver is in thermal subsystem, the TI SoC thermal, and the other two drivers are in hwmon subsystem. Actually, this would be the first step of the complete work because we still need to check other potential drivers to be converted and then validate the proposed API. But the reason why I include it in this pull request is that, first, this change does not hurt any others without using this approach, second, the principle and concept of this change would not break after converting the remaining drivers. BTW, as you can see, there are several points in this change that do not belong to thermal subsystem. Because it has been suggested by Guenter R that in such cases, it is recommended to send the complete series via one single subsystem. Specifics: - representing hardware thermal properties in device tree infrastructure - fix a regression that the imx thermal driver breaks system suspend. - introduce ACPI INT3403 thermal driver to retrieve temperature data from the INT3403 ACPI device object present on some systems. - introduce debug statement for thermal core and step_wise governor. - assorted fixes and cleanups for thermal core, cpu cooling, exynos thrmal, intel powerclamp and imx thermal driver" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (34 commits) thermal: remove const flag from .ops of imx thermal Thermal: update thermal zone device after setting emul_temp intel_powerclamp: Fix cstate counter detection. thermal: imx: add necessary clk operation Thermal cpu cooling: return error if no valid cpu frequency entry thermal: fix cpu_cooling max_level behavior thermal: rcar-thermal: Enable driver compilation with COMPILE_TEST thermal: debug: add debug statement for core and step_wise thermal: imx_thermal: add module device table drivers: thermal: Mark function as static in x86_pkg_temp_thermal.c thermal:samsung: fix compilation warning thermal: imx: correct suspend/resume flow thermal: exynos: fix error return code Thermal: ACPI INT3403 thermal driver MAINTAINERS: add thermal bindings entry in thermal domain arm: dts: make OMAP4460 bandgap node to belong to OCP arm: dts: make OMAP443x bandgap node to belong to OCP arm: dts: add cooling properties on omap5 cpu node arm: dts: add omap5 thermal data arm: dts: add omap5 CORE thermal data ...

* | thermal: exynos: boost: Automatic enable/disable of BOOST feature (at ↵Lukasz Majewski2014-01-171-6/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Exynos4412) This patch provides auto disable/enable operation for boost. It uses already present thermal infrastructure to provide BOOST hysteresis. The TMU data is modified to work properly with or without BOOST. Hence, the two first trip points with corresponding clip frequencies are adjusted. The first one is reduced from 85 to 70 degrees and the clip frequency is increased to 1.4 GHz from 800 MHz. This trip point is in fact responsible for providing BOOST hysteresis. When temperature exceeds 70 deg, the maximal non BOOST frequency for Exynos4412 is imposed. Since the first trigger level has been "stolen" for BOOST, the second one needs to be a compromise for the previously used two for non BOOST configuration. The 95 deg with modified clip freq (to 400 MHz) should provide a good balance between cooling down the overheated device and throughput on an acceptable level. Two last trigger levels are not modified since, they cause platform shutdown on emergency overheat to happen. The third trip point passage results in SW managed shut down of the system. If the last trip point is crossed, the PMU HW generates the power off signal.

| | | | | | | | | | | | | | | | | Exynos4412 The commit d0a0ce3e77c795258d47f9163e92d5031d0c5221 ("thermal: exynos: Add missing definations and code cleanup") has removed setting of test MUX address value at TMU configuration setting. This field is not present on Exynos4210 and Exynos5 SoCs. However on Exynos4412 SoC it is required to set this field after reset because without it TMU shows maximal available temperature, which causes immediate platform shutdown.

Following commit changes that, by introducing separate exynos4412_default_tmu_data structure. Since Exynos4412 was chronologically first, the corresponding name for TMU registers and default data was renamed. Additionally, new SOC_ARCH_EXYNOS4412 type has been defined.

* thermal: exynos: Remove check for thermal device pointer at ↵Lukasz Majewski2013-10-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | exynos_report_trigger() The commit 4de0bdaa9677d11406c9becb70c60887c957e1f0 ("thermal: exynos: Add support for instance based register/unregister") broke check for presence of therm_dev at global thermal zone in exynos_report_trigger(). The resulting wrong test prevents thermal_zone_device_update() call, which calls handlers for situation when trip points are passed. Such behavior prevents thermal driver from proper reaction (when TMU interrupt is raised) in a situation when overheating is detected at TMU hardware. It turns out, that after exynos thermal subsystem redesign (at v3.12) this check is not needed, since it is not possible to register thermal zone without valid thermal device.

| | | | | | | | | | | | | | | | | This patch adds support to handle multiple instances of the TMU controllers. This is done by removing the static structure to register with the core thermal and creating it dynamically for each instance of the TMU controller. The interrupt is made shared type to handle shared interrupts. Now since the ISR needs the core thermal framework to be registered so request_irq is moved after the core registration is done. Also the identifier of the TMU controller is extracted from device tree alias. This will be used for TMU specific initialisation.
