A "generic-adc-thermal" without "temperature-lookup-table" is perfectly valid since commit d36e2fa0 ("thermal: generic-adc: make lookup table optional"). On deferred probe the message "no lookup table, assuming DAC channel returns milliCelcius" is still logged. Prevent this message on deferred probe of the IIO channel by first looking up the IIO channel. Signed-off-by:

As we introduced the idle injection cooling device called cpuidle_cooling, let's be consistent and rename the cpu_cooling to cpufreq_cooling as this one mitigates with OPPs changes. Signed-off-by:

The cpu idle cooling device offers a new method to cool down a CPU by injecting idle cycles at runtime. It has some similarities with the intel power clamp driver but it is actually designed to be more generic and relying on the idle injection powercap framework. The idle injection duration is fixed while the running duration is variable. That allows to have control on the device reactivity for the user experience. An idle state powering down the CPU or the cluster will allow to drop the static leakage, thus restoring the heat capacity of the SoC. It can be set with a trip point between the hot and the critical points, giving the opportunity to prevent a hard reset of the system when the cpufreq cooling fails to cool down the CPU. With more sophisticated boards having a per core sensor, the idle cooling device allows to cool down a single core without throttling the compute capacity of several cpus belonging to the same clock line, so it could be used in collaboration with the cpufreq cooling device.

The next changes will add a new way to cool down a CPU by injecting idle cycles. With the current configuration, a CPU cooling device is the cpufreq cooling device. As we want to add a new CPU cooling device, let's convert the CPU cooling to a choice giving a list of CPU cooling devices. At this point, there is obviously only one CPU cooling device. There is no functional changes. Signed-off-by:

Tmu_get_temp will get called as a part of sensor registration via devm_thermal_zone_of_sensor_register(). To prevent it from retruning bogus data we need to enable sensor monitoring before that. Looking at the datasheet (i.MX8MQ RM) there doesn't seem to be any harm in enabling them all, so, for the sake of simplicity, change the code to do just that. Signed-off-by:

We can simplify error cleanup code if instead of passing a "struct platform_device *" to qoriq_tmu_calibration() and deriving a bunch of pointers from it, we pass those pointers directly. This way we won't be force to call platform_set_drvdata() as early in qoriq_tmu_probe() and need to have "platform_set_drvdata(pdev, NULL);" in error path. Signed-off-by:
