Or do we wait to have CPU OPPs and thermal throttling to add them? I guess you can find them either in the datasheet or in vendor tree. Thanks, Quentin

No. This is a separate, unrelated, change that has nothing to do with what is described either in the commit title or the commit log. The thermal zone itself shouldn't even be in this patch. Maxime

As we have gained the support for the thermal sensor in H3, we can now add its device nodes to the device tree. Add them to the H3 device tree. The H5 thermal sensor has some differences, and will be added furtherly.
