2016-03-18Thermal: Ignore invalid trip pointsZhang Rui1-1/+12
In some cases, platform thermal driver may report invalid trip points, thermal core should not take any action for these trip points. This fixed a regression that bogus trip point starts to screw up thermal control on some Lenovo laptops, after commit bb431ba26c5cd0a17c941ca6c3a195a3a6d5d461 Author: Zhang Rui <rui.zhang@intel.com> Date: Fri Oct 30 16:31:47 2015 +0800 Thermal: initialize thermal zone device correctly After thermal zone device registered, as we have not read any temperature before, thus tz->temperature should not be 0, which actually means 0C, and thermal trend is not available. In this case, we need specially handling for the first thermal_zone_device_update(). Both thermal core framework and step_wise governor is enhanced to handle this. And since the step_wise governor is the only one that uses trends, so it's the only thermal governor that needs to be updated.

2016-03-08thermal: exynos: Defer probe if vtmu is present but not registeredJavier Martinez Canillas1-0/+2
The driver doesn't check if the regulator_get_optional return value is -EPROBE_DEFER so it will wrongly assume that the regulator couldn't be found just because the regulator driver wasn't registered yet, i.e: exynos-tmu 10060000.tmu: Regulator node (vtmu) not found In this case the return value should be propagated to allow the driver probe function to be deferred until the regulator driver is registered.

2016-03-08thermal: exynos: Print a message about exceeded number of supported trip-pointsKrzysztof Kozlowski1-0/+15
When DeviveTree contains more trip-points than SoC can configure (usually more than four) and polling mode is not enabled, then the remaining trip-points will be silently ignored. No interrupts will be generated for them. This might be quite dangerous when one provides DTB with a non-configurable critical trip-point, like (assuming four supported thresholds in TMU): - alert @50 C (type: active), - alert @60 C (type: active), - alert @70 C (type: active), - alert @80 C (type: active), - critical @120 C (type: critical) <- no interrupts generated. This is a mistake in DTB so print a message in such case.

This fixes a problem that the system is cool, while the fan devices are left running on full speed after boot, if fan device is registered after thermal zone device.

2015-12-29Thermal: handle thermal zone device properly during system sleepZhang Rui1-0/+42
Current thermal code does not handle system sleep well because 1. the cooling device cooling state may be changed during suspend 2. the previous temperature reading becomes invalid after resumed because it is got before system sleep 3. updating thermal zone device during suspending/resuming is wrong because some devices may have already been suspended or may have not been resumed. Thus, the proper way to do this is to cancel all thermal zone device update requirements during suspend/resume, and after all the devices have been resumed, reset and update every registered thermal zone devices. This also fixes a regression introduced by: Commit 19593a1fb1f6 ("ACPI / fan: convert to platform driver") Because, with above commit applied, all the fan devices are attached to the acpi_general_pm_domain, and they are turned on by the pm_domain automatically after resume, without the awareness of thermal core.

After thermal zone device registered, as we have not read any temperature before, thus tz->temperature should not be 0, which actually means 0C, and thermal trend is not available. In this case, we need specially handling for the first thermal_zone_device_update(). Both thermal core framework and step_wise governor is enhanced to handle this. And since the step_wise governor is the only one that uses trends, so it's the only thermal governor that needs to be updated.

2015-11-23Revert "thermal: qcom_spmi: allow compile test"Arnd Bergmann1-1/+1
This just caused build errors: warning: (QCOM_SPMI_TEMP_ALARM) selects REGMAP_SPMI which has unmet direct dependencies (SPMI) drivers/built-in.o: In function `regmap_spmi_ext_gather_write': :(.text+0x609b0): undefined reference to `spmi_ext_register_write' :(.text+0x609f0): undefined reference to `spmi_ext_register_writel' While it's generally a good idea to allow compile testing, in this case, it just doesn't work, so reverting the patch that introduced the compile-test variant seems the most appropriate solution. Note that SPMI also has a 'depends on ARCH_QCOM || COMPILE_TEST' statement, so we should be able to enable SPMI on all architectures for compile testing already.

2015-11-16thermal: of-thermal: Reduce log level for message when can't fine thermal zoneJiada Wang1-1/+1
Some systems register thermal zone by themself and don't need to have thermal zones node in DT. Therefore reduce the log level from ERROR to DEBUG when thermal zone node can't be find in of_thermal_destroy_zones().

2015-11-12thermal: power_allocator: Use temperature reading from tzKapileshwar Singh1-17/+7
All thermal governors use the temperature value stored in struct thermal_zone_device. thermal_zone_device->temperature power_allocator governor should not deviate from this and use the same.

2015-11-12thermal: rockchip: Support the RK3368 SoCs in thermal driverCaesar Wang1-0/+72
The RK3368 SoCs support to 2 channel TS-ADC, the temperature criteria of each channel can be configurable. The system has two Temperature Sensors, channel 0 is for CPU, and channel 1 is for GPU. Signed-off-by: Caesar Wang <wxt@rock-chips.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2015-11-12thermal: rockchip: consistently use int for temperaturesCaesar Wang1-8/+8
As Temperature is currently represented as int not long in the thermal framework since use int intead of unsigned long/long to represent temperature to avoid bogus overheat detection when negative temperature reported.
