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

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 ...

ACPI: add ACPI_TYPE_LOCAL_REFERENCE support to acpi_extract_package()

ACPI: add dynamic_debug support

2014-05-26T12:38:57Z

Commit 1a699476e258 ("ACPI / hotplug / PCI: Hotplug notifications from acpi_bus_notify()") added debug messages for a few common events. These debug messages are unconditionally enabled if CONFIG_DYNAMIC_DEBUG is defined, contrary to the documented meaning, making the ACPI system spew lots of unwanted noise on any kernel with dynamic debugging. The bug was introduced by commit fbfddae69657 ("ACPI: Add acpi_handle_() interfaces"), which added the CONFIG_DYNAMIC_DEBUG dependency without respecting its meaning. Fix by adding real support for dynamic_debug. Fixes: fbfddae69657 ("ACPI: Add acpi_handle_() interfaces") Signed-off-by: Bjørn Mork Signed-off-by: Rafael J. Wysocki

ACPI: introduce helper interfaces for _DSM method

2014-01-05T15:07:14Z

There are several drivers making use of ACPI _DSM method to detect and invoke device specific methods. Currently every driver has implemented its private version to support ACPI _DSM method. So this patch introduces three helper functions to support ACPI _DSM method, which will be used to replace open-coded versions. It helps to simplify code and improve code readability.
