This movement is needed because the hwmon entries and corresponding sysfs interface is a duplicate of utilities already provided by driver/thermal/thermal_sys.c. The goal is to place it in thermal folder and add necessary functions to use the in-kernel thermal interfaces.

This patchset introduces a new generic cooling device based on cpufreq that can be used on non-ACPI platforms. As a proof of concept, we have drivers for the following platforms using this mechanism now: * Samsung Exynos (Exynos4 and Exynos5) in the current patchset. * Freescale i.MX (git://git.linaro.org/people/amitdanielk/linux.git imx6q_thermal) There is a small change in cpufreq cooling registration APIs, so a minor change is needed for Freescale platforms. Brief Description: 1) The generic cooling devices code is placed inside driver/thermal/* as placing inside acpi folder will need un-necessary enabling of acpi code. This code is architecture independent. 2) This patchset adds generic cpu cooling low level implementation through frequency clipping. In future, other cpu related cooling devices may be added here. An ACPI version of this already exists (drivers/acpi/processor_thermal.c) .But this will be useful for platforms like ARM using the generic thermal interface along with the generic cpu cooling devices. The cooling device registration API's return cooling device pointers which can be easily binded with the thermal zone trip points. The important APIs exposed are, a) struct thermal_cooling_device *cpufreq_cooling_register( struct cpumask *clip_cpus) b) void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev) 3) Samsung exynos platform thermal implementation is done using the generic cpu cooling APIs and the new trip type. The temperature sensor driver present in the hwmon folder(registered as hwmon driver) is moved to thermal folder and registered as a thermal driver. A simple data/control flow diagrams is shown below, Core Linux thermal <-----> Exynos thermal interface <----- Temperature Sensor | | \|/ | Cpufreq cooling device <--------------- TODO: *Will send the DT enablement patches later after the driver is merged. This patch: Add support for generic cpu thermal cooling low level implementations using frequency scaling up/down based on the registration parameters. Different cpu related cooling devices can be registered by the user and the binding of these cooling devices to the corresponding trip points can be easily done as the registration APIs return the cooling device pointer. The user of these APIs are responsible for passing clipping frequency . The drivers can also register to recieve notification about any cooling action called.

we need to go over all the thermal_instance list of a cooling device to decide which cooling state to put the cooling device to. But at this time, as a cooling device may be referenced in multiple thermal zones, we need to lock the list first in case another thermal zone is updating this cooling device.

This fixes the problem that a cooling device may be referenced by by multiple trip points in multiple thermal zones. With this patch, we have two stages for updating a thermal zone, 1. check if a thermal_instance needs to be updated or not 2. update the cooling device, based on the target cooling state of all its instances. Note that, currently, the cooling device is set to the deepest cooling state required. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Reviewed-by: Rafael J.

This function is used to update the cooling state of all the cooling devices that are bound to an active trip point. This will be used for passive cooling as well, in the future patches. as both active and passive cooling can share the same algorithm, which is 1. if the temperature is higher than a trip point, a. if the trend is THERMAL_TREND_RAISING, use higher cooling state for this trip point b. if the trend is THERMAL_TREND_DROPPING, use lower cooling state for this trip point 2. if the temperature is lower than a trip point, use lower cooling state for this trip point.

Zhang Rui authored
According to ACPI spec, tc1 and tc2 are used by OSPM to anticipate the temperature trends. We introduced the same concept to the generic thermal layer for passive cooling, but now it seems that these values are hard to be used on other platforms. So We introduce .get_trend() as a more general solution. For the platform thermal drivers that have their own way to anticipate the temperature trends, they should provide their own .get_trend() callback. Or else, we will calculate the temperature trends by simply comparing the current temperature and the cached previous temperature reading.

As the active cooling devices can have multiple cooling states, we may want only several cooling states for a certain trip point, and other cooling states for other active trip points. To do this, we should be able to describe the cooling device behavior for a certain trip point, rather than for the entire thermal zone. And when updating thermal zone, we need to check the upper and lower limit to make sure the cooling device is set to the proper cooling state. Note that this patch will not bring any different behavior as upper limit is set to max_state and lower limit is set to 0 in this patch, for now. Next patch will set these to real values.

Pull ARM DMA engine updates from Russell King: "This looks scary at first glance, but what it is is: - a rework of the sa11x0 DMA engine driver merged during the previous cycle, to extract a common set of helper functions for DMA engine implementations. - conversion of amba-pl08x.c to use these helper functions. - addition of OMAP DMA engine driver (using these helper functions), and conversion of some of the OMAP DMA users to use DMA engine. Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."
