2020-03-23thermal: imx8mm: Add i.MX8MP supportAnson Huang
i.MX8MP shares same TMU with i.MX8MM, the only difference is i.MX8MP has two thermal sensors while i.MX8MM ONLY has one, add multiple sensors support for i.MX8MM TMU driver.

2020-03-23thermal: qcom: tsens.h: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2020-03-20dt-bindings: thermal: make cooling-maps property optionalYuantian Tang
Cooling-maps doesn't have to be a required property because there may be no cooling device on system, or there are no enough cooling devices for each thermal zone in multiple thermal zone cases since cooling devices can't be shared. So make this property optional to remove such limitations. For thermal zones with no cooling-maps, there could be critic trips that can trigger CPU reset or shutdown. So they still can take actions.

2020-03-12thermal: imx_sc: add i.MX system controller thermal supportAnson Huang
i.MX8QXP is an ARMv8 SoC which has a Cortex-M4 system controller inside, the system controller is in charge of controlling power, clock and thermal sensors etc.. This patch adds i.MX system controller thermal driver support, Linux kernel has to communicate with system controller via MU (message unit) IPC to get each thermal sensor's temperature, it supports multiple sensors which are passed from device tree, please see the binding doc for details.

2020-03-12thermal: of-thermal: add API for getting sensor ID from DTAnson Huang
This patch adds new API thermal_zone_of_get_sensor_id() to provide the feature of getting sensor ID from DT thermal zone's node. It's useful for thermal driver to register the specific thermal zone devices from DT in a common way.

2020-03-12thermal: rcar_gen3_thermal: Generate interrupt when temperature changesNiklas Söderlund
The desired behavior of the driver is to generate an interrupt and call thermal_zone_device_update() as soon as the temperature have changed more then one degree. When the set_trips operation was implemented it was believed that the trip window set by the framework would move around the current temperature and the hysteresis value described in devicetree. The behavior of the framework is however to set a window based on the trip points described in devicetree. Remove the set_trips operation which was not used correctly and update the temperatures that triggers interrupts directly from the interrupt handler.
