Pull thermal management updates from Zhang Rui: - Fix a problem where orderly_shutdown() is called for multiple times due to multiple critical overheating events raised in a short period by platform thermal driver. (Keerthy) - Introduce a backup thermal shutdown mechanism, which invokes kernel_power_off()/emergency_restart() directly, after orderly_shutdown() being issued for certain amount of time(specified via Kconfig). This is useful in certain conditions that userspace may be unable to power off the system in a clean manner and leaves the system in a critical state, like in the middle of driver probing phase. (Keerthy) - Introduce a new interface in thermal devfreq_cooling code so that the driver can provide more precise data regarding actual power to the thermal governor every time the power budget is calculated. (Lukasz Luba) - Introduce BCM 2835 soc thermal driver and northstar thermal driver, within a new sub-folder. (Rafał Miłecki) - Introduce DA9062/61 thermal driver. (Steve Twiss) - Remove non-DT booting on TI-SoC driver. Also add support to fetching coefficients from DT. (Keerthy) - Refactorf RCAR Gen3 thermal driver. (Niklas Söderlund) - Small fix on MTK and intel-soc-dts thermal driver.

thermal: da9062/61: Thermal junction temperature monitoring driver

2017-04-07T04:48:03+00:00

Add junction temperature monitoring supervisor device driver, compatible with the DA9062 and DA9061 PMICs. A MODULE_DEVICE_TABLE() macro is added. If the PMIC's internal junction temperature rises above T_WARN (125 degC) an interrupt is issued. This T_WARN level is defined as the THERMAL_TRIP_HOT trip-wire inside the device driver. The thermal triggering mechanism is interrupt based and happens when the temperature rises above a given threshold level. The component cannot return an exact temperature, it only has knowledge if the temperature is above or below a given threshold value. A status bit must be polled to detect when the temperature falls below that threshold level again. A kernel work queue is configured to repeatedly poll and detect when the temperature falls below this trip-wire, between 1 and 10 second intervals (defaulting at 3 seconds). This scheme is provided as an example. It would be expected that any final implementation will also include a notify() function and any of these settings could be altered to match the application where appropriate. When over-temperature is reached, the interrupt from the DA9061/2 will be repeatedly triggered. The IRQ is therefore disabled when the first over-temperature event happens and the status bit is polled using a work-queue until it becomes false. This strategy is designed to allow the periodic transmission of uevents (HOT trip point) as the first level of temperature supervision method. It is intended for non-invasive temperature control, where the necessary measures for cooling the system down are left to the host software. Once the temperature falls again, the IRQ is re-enabled so a new critical over-temperature event can be detected. Reviewed-by: Lukasz Luba Signed-off-by: Steve Twiss Signed-off-by: Eduardo Valentin

cpufreq: dbx500: Manage cooling device from cpufreq driver

2017-03-15T23:14:31+00:00

The best place to register the CPU cooling device is from the cpufreq driver as we would know if all the resources are already available or not. That's what is done for the cpufreq-dt.c driver as well. The cpu-cooling driver for dbx500 platform was just (un)registering with the thermal framework and that can be handled easily by the cpufreq driver as well and in proper sequence as well. Get rid of the cooling driver and its its users and manage everything from the cpufreq driver instead. Signed-off-by: Viresh Kumar Tested-by: Linus Walleij Signed-off-by: Rafael J. Wysocki
