thermal/drivers/loongson-2: Add thermal management support

2023-08-17T07:27:18+00:00

This patch adds the support for Loongson-2 thermal sensor controller, which can support maximum four sensor selectors that corresponding to four sets of thermal control registers and one set of sampling register. The sensor selector can selector a speific thermal sensor as temperature input. The sampling register is used to obtain the temperature in real time, the control register GATE field is used to set the threshold of high or low temperature, when the input temperature is higher than the high temperature threshold or lower than the low temperature threshold, an interrupt will occur.

thermal: Allow selecting the bang-bang governor as default

2023-06-26T10:03:13+00:00

For many setups the bang-bang governor is exactly what we want. Many ARM SoC-based devices use fans to cool down the entire SoC and that works well only with the bang-bang governor because it uses the hysteresis in order to let the fan run for a while to cool the SoC down below the trip point before switching it off again. The step-wise governor will behave strangely in these situations. It doesn't use the hysteresis, so it can lead to situations where the fan is turned on for only a very brief period and then is switched back off, only to get switched back on again very quickly because the SoC hasn't cooled down very much.

thermal/drivers/mediatek: Relocate driver to mediatek folder

2023-02-15T16:28:25+00:00

Add MediaTek proprietary folder to upstream more thermal zone and cooler drivers, relocate the original thermal controller driver to it, and rename it as "auxadc_thermal.c" to show its purpose more clearly.

thermal: Drop obsolete dependency on COMPILE_TEST

2022-08-03T17:15:31+00:00

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. Signed-off-by: Jean Delvare Signed-off-by: Rafael J. Wysocki

thermal/governor: Remove deprecated information

2022-04-22T14:47:40+00:00

The userspace governor is still in use on production systems and the deprecating warning is scary. Even if we want to get rid of the userspace governor, it is too soon yet as the alternatives are not yet adopted. Change the deprecated warning by an information message suggesting to switch to the netlink thermal events.

thermal/drivers: Add TSU driver for RZ/G2L

2021-11-30T16:27:56+00:00

The RZ/G2L SoC incorporates a thermal sensor unit (TSU) that measures the temperature inside the LSI. The thermal sensor in this unit measures temperatures in the range from −40 degree Celsius to 125 degree Celsius with an accuracy of ±3°C. The TSU repeats measurement at 20 microseconds intervals and automatically updates the results of measurement. The TSU has no interrupts as well as no external pins. This patch adds Thermal Sensor Unit(TSU) driver for RZ/G2L SoC.
