Currently after store trip points number in 'ret', it is overwritten afterwards, this cause incorrect trip point number always be shown in the debug information after register of each thermal zone.

2019-05-14thermal: cpu_cooling: Actually trace CPU load in thermal_power_cpu_get_powerMatthias Kaehlcke
The CPU load values passed to the thermal_power_cpu_get_power tracepoint are zero for all CPUs, unless, unless the thermal_power_cpu_limit tracepoint is enabled too: irq/41-rockchip-98 [000] .... 290.972410: thermal_power_cpu_get_power: cpus=0000000f freq=1800000 load={{0x0,0x0,0x0,0x0}} dynamic_power=4815 vs irq/41-rockchip-96 [000] .... 95.773585: thermal_power_cpu_get_power: cpus=0000000f freq=1800000 load={{0x56,0x64,0x64,0x5e}} dynamic_power=4959 irq/41-rockchip-96 [000] .... 95.773596: thermal_power_cpu_limit: cpus=0000000f freq=408000 cdev_state=10 power=416 There seems to be no good reason for omitting the CPU load information depending on another tracepoint. My guess is that the intention was to check whether thermal_power_cpu_get_power is (still) enabled, however 'load_cpu != NULL' already indicates that it was at least enabled when cpufreq_get_requested_power() was entered, there seems little gain from omitting the assignment if the tracepoint was just disabled, so just remove the check.

2019-05-14thermal: rockchip: fix up the tsadc pinctrl setting errorElaine Zhang
Explicitly use the pinctrl to set/unset the right mode instead of relying on the pinctrl init mode. And it requires setting the tshut polarity before select pinctrl. When the temperature sensor mode is set to 0, it will automatically reset the board via the Clock-Reset-Unit (CRU) if the over temperature threshold is reached. However, when the pinctrl initializes, it does a transition to "otp_out" which may lead the SoC restart all the time. "otp_out" IO may be connected to the RESET circuit on the hardware. If the IO is in the wrong state, it will trigger RESET. (similar to the effect of pressing the RESET button) which will cause the soc to restart all the time.

2019-05-14thermal: rcar_gen3_thermal: fix interrupt typeJiada Wang
Currently IRQF_SHARED type interrupt line is allocated, but it is not appropriate, as the interrupt line isn't shared between different devices, instead IRQF_ONESHOT is the proper type. By changing interrupt type to IRQF_ONESHOT, now irq handler is no longer needed, as clear of interrupt status can be done in threaded interrupt context. Because IRQF_ONESHOT type interrupt line is kept disabled until the threaded handler has been run, so there is no need to protect read/write of REG_GEN3_IRQSTR with lock.

2019-05-14thermal: Introduce devm_thermal_of_cooling_device_registerGuenter Roeck
thermal_of_cooling_device_register() and thermal_cooling_device_register() are typically called from driver probe functions, and thermal_cooling_device_unregister() is called from remove functions. This makes both a perfect candidate for device managed functions. Introduce devm_thermal_of_cooling_device_register(). This function can also be used to replace thermal_cooling_device_register() by passing a NULL pointer as device node. The new function requires both struct device * and struct device_node * as parameters since the struct device_node * parameter is not always identical to dev->of_node. Don't introduce a device managed remove function since it is not needed at this point. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
