This series allows to specify the imx thermal drivers trip point from the device tree, without this change the threshold are hard-coded and this might not be correct given the thermal design of the final system. This change is backward compatible with the existing device tree, and even with this change in by default the thresholds are the same as before. Toradex board are also updated to use a system-specific thresholds. Discussion on the current design is here: https://lore.kernel.org/all/4ba1d7d2-3e8c-ba60-37fd-9598f415c076@xxxxxxxxxx/ One side note, after this change the dtbs checker starts complaining with this message ``` linux/arch/arm/boot/dts/imx6dl-alti6p.dtb: tempmon: '#thermal-sensor-cells' does not match any of the regexes: '^(automotive|commercial|extended-commercial|industrial)-thermal$', 'pinctrl-[0-9]+' From schema: linux/Documentation/devicetree/bindings/thermal/imx-thermal.yaml ``` to my understanding this is just a side effect, '#thermal-sensor-cells' is not changed in any way by this series. I can fix that, I wonder if I should remove the property from the imx dtsi files or add it to the binding yaml definition, not sure about it. Anybody can advise?
