If not, we should definitely update all the relevant SoCs. Konrad

We should be able to do that on all platforms with working interrupts, no? [*] Some of the zones has a passive timeout of 10? That said, as above. Would you like me to fix that now? Regards, Bjorn

Did you determine whether the interrupts work as expected? We don't want to be polling here unless we have to (i.e. polling-delay should be 0 as per the binding). Johan

The SC8280XP contains two additional tsens instances, providing among other things thermal measurements for the GPU. Add these and a GPU thermal-zone.
