All six sensors has been given 4 bytes of memory in DDR to write temperature in millivolts. This thermal driver read temperature values from DDR because no direct access to sensors. Like this all temparature sensors are monitored and trips at critical temperature. If driver can't handle thermal runaways because of any unknown reason, then firmware in m0 Processor will handle.

2019-01-29thermal: cpu_cooling: Require thermal core to be compiled inAmit Kucheria1-0/+1
The CPU cooling driver (cpu_cooling.c) allows the platform's cpufreq driver to register as a cooling device and cool down the platform by throttling the CPU frequency. In order to be able to auto-register a cpufreq driver as a cooling device from the cpufreq core, we need access to code inside cpu_cooling.c which, in turn, accesses code inside thermal core. CPU_FREQ is a bool while THERMAL is tristate. In some configurations (e.g. allmodconfig), CONFIG_THERMAL ends up as a module while CONFIG_CPU_FREQ is compiled in. This leads to following error: drivers/cpufreq/cpufreq.o: In function `cpufreq_offline': cpufreq.c:(.text+0x407c): undefined reference to `cpufreq_cooling_unregister' drivers/cpufreq/cpufreq.o: In function `cpufreq_online': cpufreq.c:(.text+0x70c0): undefined reference to `of_cpufreq_cooling_register' Given that platforms using CPU_THERMAL usually want it compiled-in so it is available early in boot, make CPU_THERMAL depend on THERMAL being compiled-in instead of allowing it to be a module. As a result of this change, get rid of the ugly (!CPU_THERMAL || THERMAL) dependency in all cpufreq drivers using CPU_THERMAL. Suggested-by: Rafael J.

2019-01-18drivers: thermal: int340x_thermal: Fix sysfs race conditionAaron Hill1-13/+15
Changes since V1: * Use dev_info instead of printk * Use dev_warn instead of BUG_ON Previously, sysfs_create_group was called before all initialization had fully run - specifically, before pci_set_drvdata was called. Since the sysctl group is visible to userspace as soon as sysfs_create_group returns, a small window of time existed during which a process could read from an uninitialized/partially-initialized device. This commit moves the creation of the sysctl group to after all initialized is completed. This ensures that it's impossible for userspace to read from a sysctl file before initialization has fully completed. To catch any future regressions, I've added a check to ensure that proc_thermal_emum_mode is never PROC_THERMAL_NONE when a process tries to read from a sysctl file. Previously, the aforementioned race condition could result in the 'else' branch running while PROC_THERMAL_NONE was set, leading to a null pointer deference.

First correct the edge case to return the last element if we're outside the range, rather than at the last element, so that interpolation is not omitted for points between the two last entries in the table. Then correct the formula to perform linear interpolation based the two points surrounding the read ADC value. The indices for temp are kept as "hi" and "lo" to pair with the adc indices, but there's no requirement that the temperature is provided in descendent order. mult_frac() is used to prevent issues with overflowing the int.

2019-01-02thermal: armada: add overheat interrupt supportMiquel Raynal1-1/+269
The IP can manage to trigger interrupts on overheat situation from all the sensors. However, the interrupt source changes along with the last selected source (ie. the last read sensor), which is an inconsistent behavior. Avoid possible glitches by always selecting back only one channel which will then be referenced as the "overheat_sensor" (arbitrarily: the first in the DT which has a critical trip point filled in). It is possible that the scan of all thermal zone nodes did not bring a critical trip point from which the overheat interrupt could be configured. In this case just complain but do not fail the probe. Also disable sensor switch during overheat situations because changing the channel while the system is too hot could clear the overheat state by changing the source while the temperature is still very high. Even if the overheat state is not declared, overheat interrupt must be cleared by reading the DFX interrupt cause _after_ the temperature has fallen down to the low threshold, otherwise future possible interrupts would not be served. A work polls the corresponding register until the overheat flag gets cleared in this case.

2018-12-10thermal/drivers/hisi: Fix wrong platform_get_irq_byname()Daniel Lezcano1-1/+1
Without this patch, the thermal driver on hi6220 and hi3660 is broken. That is due because part of the posted patchset was merged but a small change in the DT was dropped. The hi6220 and hi3660 do not have an interrupt name in the DT, so finding interrupt by name fails. Fix this by returning back to the platform_get_irq() function call.

2018-12-07drivers: thermal: Move QCOM_SPMI_TEMP_ALARM into the qcom subdirAmit Kucheria5-13/+13
This cleans up the directory a bit allowing just one place to look for thermal related drivers for QCOM platforms instead of being scattered in the root directory and the qcom/ subdirectory. Compile-tested with ARCH=arm64 defconfig and the driver explicitly enabled with menuconfig.

2018-12-07drivers: thermal: Move various drivers for intel platforms into a subdirAmit Kucheria23-86/+95
This cleans up the directory a bit, now that we have several other platforms using platform-specific sub-directories. Compile-tested with ARCH=x86 defconfig and the drivers explicitly enabled with menuconfig.

2018-12-05thermal: broadcom: constify thermal_zone_of_device_ops structureJulia Lawall1-1/+1
The thermal_zone_of_device_ops structure can be const as it is only passed as the last argument of thermal_zone_of_sensor_register and the corresponding parameter is declared as const. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Reviewed-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
