2014-03-10thermal: core: use cancel delayed work syncDiwakar Tundlam
This fixes an issue with race between a piece of delayed work in progress and its cancellation during sensor shutdown that happens as part of system power-down. We refactor the code a bit to make sure the cancel_sync is called outside the tz mutex to prevent deadlock. This was found during a stress test by continuously running warm-reboot in a loop. We found that eventually, we get a system hang or crash with an error message from a failed reading of the temp from the get_temp API which indicates a potential issue with the polling work function. We can accelerate the reproduction of the issue by introducing an artificial delay in the work function and forcing polling by setting a non-zero polling_delay for the thermal zone. In the actual system, the timing differences could be introduced from other unresolved errors in the I2C bus transactions which could show up during the cold and warm reboot stress tests.

This patch introduces a thermal data parser for device tree. The parsed data is used to build thermal zones and thermal binding parameters. The output data can then be used to deploy thermal policies. This patch adds also documentation regarding this API and how to define tree nodes to use this infrastructure. Note that, in order to be able to have control on the sensor registration on the DT thermal zone, it was required to allow changing the thermal zone .get_temp callback. For this reason, this patch also removes the 'const' modifier from the .ops field of thermal zone devices.

This reverts NVIDIA downstream commit d2ad63cf30463fb24f4cf645b6cc4523ab39fdee, since it's been replaced by the upstream commit a9f2d19ba7be38590c84487359891d45a66b62f4 (thermal: Fix binding problem when there is thermal zone params). In the same patch, we replace it with the upstream commit. This is to attempt to preserve bisectability: "The thermal zone params can be used to set governor to specific thermal governor for thermal zone device. But if the thermal zone params has only governor name without thermal bind params, then the thermal zone device will not be binding to cooling device. Because tz->ops->bind operator is not invoked in bind_tz() and bind_cdev() when there is thermal zone params."

2014-02-13Thermal: Check for validity before doing kfreeDurgadoss R
The thermal_release function is called whenever any device belonging to 'thermal' class unregisters. This function performs kfree(cdev) without any check. In cases where there are more device registrations other than just 'thermal_zone' and 'cooling_device' this might accidently free memory allocated them silently; and cause memory errors. This patch changes this behavior by doing kfree(cdev) only when the device pointer belongs to a real cdev i.e. cooling_device.

2014-02-13Thermal/cpu_cooling: Return directly for the cpu out of allowed_cpus in the ↵Lan Tianyu
cpufreq_thermal_notifier() cpufreq_thermal_notifier() is to change the cpu's cpufreq in the allowed_cpus mask when associated thermal-cpufreq cdev's cooling state is changed. It's a cpufreq policy notifier handler and it will be triggered even if those cpus out of allowed_cpus has changed freq policy. cpufreq_thermal_notifier() checks the policy->cpu. If it belongs to allowed_cpus, change max_freq(default to 0) to the desire cpufreq value and pass 0 and max_freq to cpufreq_verify_within_limits() as cpufreq scope. But if not, do nothing and max_freq will remain 0. This will cause the cpufreq scope to become 0~0. This is not right. This patch is to return directly after finding cpu not belonging to allowed_cpus.

2014-02-10thermal: 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.

2014-02-10thermal: cpu_cooling: fix 'descend' check in get_property()Shawn Guo
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. Fix it by correcting the 'descend' check in if-condition to 'descend == -1'.
