2016-03-06iwlwifi: mvm: avoid panics with thermal device usageEmmanuel Grumbach1-26/+31
Thermal zone device registration can fail, and in this case we don't want to remove WiFi functionality. This is why the thermal zone registration function is void, and the flows continue even if the thermal zone device registration failed. Same applies for the cooling device. This means that we at least need to remember that the thermal zone device didn't register properly and take the minimal precautions to avoid panic'ing when we access it. This was missing.

2016-02-27iwlwifi: mvm: add registration to cooling deviceChaya Rachel Ivgi1-0/+147
Register cooling device in order to have the Thermal Manager handle the device's power budget according to the sent notifications. The interface adds a new thermal cooling device to /sys/class/thermal/ folder.

2016-02-27iwlwifi: mvm: add registration to thermal zoneChaya Rachel Ivgi1-10/+277
Register to thermal_zone interface and implement the thermal ops. The thermal handles the device throttling, and sets the the temperature thresholds the Thermal Manager would be notified of crossing. The thermal interface adds a new thermal zone device sensor under /sys/class/thermal/ folder.

2016-02-27iwlwifi: mvm: add CT-KILL notificationChaya Rachel Ivgi1-1/+26
Up to today the driver was notified of the temperature from the FW and decided whether to enter CT-kill or not. From now on, the FW will decide when to enter CT-kill and will notify the driver. Add support for this notification.

2016-02-01iwlwifi: mvm: add support for negative temperaturesChaya Rachel Ivgi1-9/+8
The driver should support also negative temperatures. So there is a need to separate between the return value and temperature in order to be able to distinguish between a negative temperature and error value.

2016-01-07iwlwifi: mvm: check minimum temperature notification lengthJohannes Berg1-1/+1
This notification will be extended with extra data, so just check that it has a minimum length, not the exact length; we might later add handling for the extra fields added and have more code to handle both versions.
