docs: thermal: convert to ReST

2019-06-27T13:22:15Z

Rename the thermal documentation files to ReST, add an index for them and adjust in order to produce a nice html output via the Sphinx build system. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

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

2019-05-16T23:16:18Z

Pull thermal management updates from Zhang Rui: - Remove the 'module' Kconfig option for thermal subsystem framework because the thermal framework are required to be ready as early as possible to avoid overheat at boot time (Daniel Lezcano) - Fix a bug that thermal framework pokes disabled thermal zones upon resume (Wei Wang) - A couple of cleanups and trivial fixes on int340x thermal drivers (Srinivas Pandruvada, Zhang Rui, Sumeet Pawnikar) * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: drivers: thermal: processor_thermal: Downgrade error message mlxsw: Remove obsolete dependency on THERMAL=m hwmon/drivers/core: Simplify complex dependency thermal/drivers/core: Fix typo in the option name thermal/drivers/core: Remove depends on THERMAL in Kconfig thermal/drivers/core: Remove module unload code thermal/drivers/core: Remove the module Kconfig's option thermal: core: skip update disabled thermal zones after suspend thermal: make device_register's type argument const thermal: intel: int340x: processor_thermal_device: simplify to get driver data thermal/int3403_thermal: favor _TMP instead of PTYP

thermal: Introduce devm_thermal_of_cooling_device_register

2019-05-14T14:00:30Z

thermal_of_cooling_device_register() and thermal_cooling_device_register() are typically called from driver probe functions, and thermal_cooling_device_unregister() is called from remove functions. This makes both a perfect candidate for device managed functions. Introduce devm_thermal_of_cooling_device_register(). This function can also be used to replace thermal_cooling_device_register() by passing a NULL pointer as device node. The new function requires both struct device * and struct device_node * as parameters since the struct device_node * parameter is not always identical to dev->of_node. Don't introduce a device managed remove function since it is not needed at this point. Signed-off-by: Guenter Roeck Signed-off-by: Eduardo Valentin

thermal: Add cooling device's statistics in sysfs

2018-04-02T13:49:01Z

This extends the sysfs interface for thermal cooling devices and exposes some pretty useful statistics. These statistics have proven to be quite useful specially while doing benchmarks related to the task scheduler, where we want to make sure that nothing has disrupted the test, specially the cooling device which may have put constraints on the CPUs. The information exposed here tells us to what extent the CPUs were constrained by the thermal framework. The write-only "reset" file is used to reset the statistics. The read-only "time_in_state_ms" file shows the time (in msec) spent by the device in the respective cooling states, and it prints one line per cooling state. The read-only "total_trans" file shows single positive integer value showing the total number of cooling state transitions the device has gone through since the time the cooling device is registered or the time when statistics were reset last. The read-only "trans_table" file shows a two dimensional matrix, where an entry (row i, column j) represents the number of transitions from State_i to State_j. This is how the directory structure looks like for a single cooling device: $ ls -R /sys/class/thermal/cooling_device0/ /sys/class/thermal/cooling_device0/: cur_state max_state power stats subsystem type uevent /sys/class/thermal/cooling_device0/power: autosuspend_delay_ms runtime_active_time runtime_suspended_time control runtime_status /sys/class/thermal/cooling_device0/stats: reset time_in_state_ms total_trans trans_table This is tested on ARM 64-bit Hisilicon hikey620 board running Ubuntu and ARM 64-bit Hisilicon hikey960 board running Android.

thermal : Remove const to make same prototype

2017-10-17T07:52:57Z

Here, prototype of thermal_zone_device_register is not matching with static inline thermal_zone_device_register. One is using const thermal_zone_params. Other is using non-const. Signed-off-by: Arvind Yadav Signed-off-by: Zhang Rui

thermal: int3400_thermal: process "thermal table changed" event

2017-08-11T02:51:22Z

Some BIOS implement ACPI notification code 0x83 to indicate active relationship table(ART) and/or thermal relationship table(TRT) changes to INT3400 device. This event needs to be propagated to user space so that it can be handled by the user space thermal daemon. Signed-off-by: Brian Bian Signed-off-by: Zhang Rui

thermal core: convert ID allocation to IDA

2017-01-04T04:47:28Z

The thermal core does not use the ability to look up pointers by ID, so convert it from using an IDR to the more space-efficient IDA. Signed-off-by: Matthew Wilcox Signed-off-by: Zhang Rui
