[PATCH] arm64: dts: qcom: purwa-iot-evk: Update TSENS thermal zone

Posted by Gaurav Kohli 2 months ago

Purwa IOT boards support a different thermal junction temperature
specification compared to the base Purwa platform due to package
level differences.

Update the passive trip thresholds to 105°C to align with the higher
temperature specification.

Is it a property of the SKU used in the EVK or a property of the overall
form factor, cooling, etc.? In the former case it should go to
purwa-iot-som.dtsi.

thanks Dmitry for review.
it is applicable for overall form factor, 2nd one is applicable here.

thanks
