kernel/git/stable/linux.git/drivers/thermal/Kconfig, branch linux-3.18.y

Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux

2014-10-24T18:21:43+00:00

Pull thermal management updates from Zhang Rui: "Sorry that I missed the merge window as there is a bug found in the last minute, and I have to fix it and wait for the code to be tested in linux-next tree for a few days. Now the buggy patch has been dropped entirely from my next branch. Thus I hope those changes can still be merged in 3.18-rc2 as most of them are platform thermal driver changes. Specifics: - introduce ACPI INT340X thermal drivers. Newer laptops and tablets may have thermal sensors and other devices with thermal control capabilities that are exposed for the OS to use via the ACPI INT340x device objects. Several drivers are introduced to expose the temperature information and cooling ability from these objects to user-space via the normal thermal framework. From: Lu Aaron, Lan Tianyu, Jacob Pan and Zhang Rui. - introduce a new thermal governor, which just uses a hysteresis to switch abruptly on/off a cooling device. This governor can be used to control certain fan devices that can not be throttled but just switched on or off. From: Peter Feuerer. - introduce support for some new thermal interrupt functions on i.MX6SX, in IMX thermal driver. From: Anson, Huang. - introduce tracing support on thermal framework. From: Punit Agrawal. - small fixes in OF thermal and thermal step_wise governor" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (25 commits) Thermal: int340x thermal: select ACPI fan driver Thermal: int3400_thermal: use acpi_thermal_rel parsing APIs Thermal: int340x_thermal: expose acpi thermal relationship tables Thermal: introduce int3403 thermal driver Thermal: introduce INT3402 thermal driver Thermal: move the KELVIN_TO_MILLICELSIUS macro to thermal.h ACPI / Fan: support INT3404 thermal device ACPI / Fan: add ACPI 4.0 style fan support ACPI / fan: convert to platform driver ACPI / fan: use acpi_device_xxx_power instead of acpi_bus equivelant ACPI / fan: remove no need check for device pointer ACPI / fan: remove unused macro Thermal: int3400 thermal: register to thermal framework Thermal: int3400 thermal: add capability to detect supporting UUIDs Thermal: introduce int3400 thermal driver ACPI: add ACPI_TYPE_LOCAL_REFERENCE support to acpi_extract_package() ACPI: make acpi_create_platform_device() an external API thermal: step_wise: fix: Prevent from binary overflow when trend is dropping ACPI: introduce ACPI int340x thermal scan handler thermal: Added Bang-bang thermal governor ...

Thermal: int340x thermal: select ACPI fan driver

2014-10-17T06:30:41+00:00

we share the same driver for both ACPI predefined Fan device and INT3404 Fan device, thus we should select the ACPI Fan driver when int340x thermal drivers are enabeld. Signed-off-by: Zhang Rui

Thermal: int340x_thermal: expose acpi thermal relationship tables

2014-10-11T01:35:48+00:00

ACPI 4.0 introduced two thermal relationship tables via _ART (active cooling) and _TRT (passive cooling) objects. These tables contain many to many relationships among thermal sensors and cooling devices. This patch parses _ART and _TRT and makes the result available to the userspace via an misc device interface. At the same time, kernel drivers can also request parsing results from internal kernel APIs. The results include source and target devices, influence, and sampling rate in case of _TRT. For _ART, the result shows source device, target device, and weight percentage. Signed-off-by: Jacob Pan Signed-off-by: Zhang Rui

Thermal: introduce int3403 thermal driver

2014-10-11T01:35:36+00:00

ACPI INT3403 device object can be used to retrieve temperature date from temperature sensors present in the system, and to expose device' performance control. The previous INT3403 thermal driver supports temperature reporting only, thus remove it and introduce this new & enhanced one. Signed-off-by: Lan Tianyu Signed-off-by: Zhang Rui

Thermal: introduce int3400 thermal driver

2014-10-10T05:57:09+00:00

Introduce int3400 thermal driver. And make INT3400 driver enumerate the other int340x thermal components shown in _ART/_TRT. Signed-off-by: Zhang Rui

ACPI: introduce ACPI int340x thermal scan handler

2014-09-11T15:35:15+00:00

Newer laptops and tablets that use ACPI may have thermal sensors and other devices with thermal control capabilities outside the core CPU/SOC, for thermal safety reasons. They are exposed for the OS to use via 1) INT3400 ACPI device object as the master. 2) INT3401 ~ INT340B ACPI device objects as the slaves. This patch introduces a scan handler to enumerate the INT3400 ACPI device object to platform bus, and prevent its slaves from being enumerated before the controller driver being probed.

thermal: Remove ARCH_KIRKWOOD dependency

2014-09-09T14:39:21+00:00

mach-kirkwood has been removed, now that kirkwood lives in mach-mvebu. Depend on MACH_KIRKWOOD, which will be set when kirkwood is built as part of ARCH_MVEBU.

thermal: Added Bang-bang thermal governor

2014-08-27T07:45:58+00:00

The bang-bang thermal governor uses a hysteresis to switch abruptly on or off a cooling device. 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. For those special devices the driver needs to explicitely request it.
