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 ... --- 91466574be1a3701fab4abf5ac1539b556575a81 diff --cc drivers/cpufreq/Kconfig index d100926,6b8cde5..4b029c0 --- a/drivers/cpufreq/Kconfig +++ b/drivers/cpufreq/Kconfig @@@ -185,8 -181,7 +185,8 @@@ config CPU_FREQ_GOV_CONSERVATIV config GENERIC_CPUFREQ_CPU0 tristate "Generic CPU0 cpufreq driver" - depends on HAVE_CLK && REGULATOR && OF - depends on HAVE_CLK && REGULATOR && PM_OPP && OF && THERMAL && CPU_THERMAL ++ depends on HAVE_CLK && REGULATOR && OF && THERMAL && CPU_THERMAL + select PM_OPP help This adds a generic cpufreq driver for CPU0 frequency management.
