2013-07-22Thermal: Fix lockup of cpu_down()Steven Rostedt
Commit f1a18a105 "Thermal: CPU Package temperature thermal" had code that did a get_online_cpus(), run a loop and then do a put_online_cpus(). The problem is that the loop had an error exit that would skip the put_online_cpus() part. In the error exit part of the function, it also did a get_online_cpus(), run a loop and then put_online_cpus(). The only way to get to the error exit part is with get_online_cpus() already performed. If this error condition is hit, the system will be prevented from taking CPUs offline. The process taking the CPU offline will lock up hard. Removing the get_online_cpus() removes the lockup as the hotplug CPU refcount is back to zero. This was bisected with ktest.

2013-07-16Thermal: x86_pkg_temp: Limit number of pkg temp zonesSrinivas Pandruvada
Although it is unlikley that physical package id is set to some arbitary number, it is better to prevent in anycase. Since package temp zones use this in thermal zone type and for allocation, added a limit.

2013-07-15Thermal: x86 package temp thermal crashSrinivas Pandruvada
On systems with no package MSR support this caused crash as there is a bug in the logic to check presence of DTHERM and PTS feature together. Added a change so that when there is no PTS support, module doesn't get loaded. Even if some CPU comes online with the PTS feature disabled, and other CPUs has this support, this patch will still prevent such MSR accesses.

2013-07-08thermal: ti-soc-thermal: use standard GPIO DT bindingsEduardo Valentin
This change updates the ti-soc-thermal driver to use standard GPIO DT bindings to read the GPIO number associated to thermal shutdown IRQ, in case the device features it. Previously, the code was using a specific DT bindings. As now OMAP supports the standard way to model GPIOs, there is no point in having a ti specific binding.

Fix build error in x86_pkg_temp_thermal.c. It requires that X86_MCE & X86_THERMAL_VECTOR be enabled, so depend on the latter symbol, since it depends on X86_MCE (indirectly). Also, X86_PKG_TEMP_THERMAL is already inside an "if THERMAL" block, so remove that duplicated dependency.

This driver register CPU digital temperature sensor as a thermal zone at package level. Each package will show up as one zone with at max two trip points. These trip points can be both read and updated. Once a non zero value is set in the trip point, if the package package temperature goes above or below this setting, a thermal notification is generated.

2013-06-13thermal: consider emul_temperature while computing trendEduardo Valentin
In case emulated temperature is in use, using the trend provided by driver layer can lead to bogus situation. In this case, debugger user would set a temperature value, but the trend would be from driver computation. To avoid this situation, this patch changes the get_tz_trend() to consider the emulated temperature whenever that is in use.

2013-06-13thermal: ti-soc-thermal: remove usage of IS_ERR_OR_NULLEduardo Valentin
This patch changes the driver to avoid the usage of IS_ERR_OR_NULL() macro. This macro can lead to dangerous results, like returning success (0) during a failure scenario (NULL pointer handling). For this reason this patch is changing the driver after revisiting the code. These are the cases: i. For cases in which IS_ERR_OR_NULL() is used for checking return values of functions that returns either PTR_ERR() or a valid pointer, it has been translated to IS_ERR() check only. ii. For cases that a NULL check is still needed, it has been translated to if (!ptr || IS_ERR(ptr)).

The variable 'descend' is initialized as -1 in function get_property(), and will never get any chance to be updated by the following code. if (freq != CPUFREQ_ENTRY_INVALID && descend != -1) descend = !!(freq > table[i].frequency); This makes function get_property() return the wrong frequency for given cooling level if the frequency table is sorted in ascending.
