There are some mistakes in the thermal trip points currently used on X1E80100. Several of the critical trip points are too high, so the hardware will trigger an emergency reset before the kernel has the chance to shutdown cleanly. We're also missing GPU cooling in the device tree, which prevents running certain GPU-intensive applications without reaching the critical shutdown temperatures. The CPU on the other hand throttles itself automatically, so we can just drop the passive trip points there. This series addresses these problems. It's quite similar to Neil's thermal zone rework for SM8650 [1], which provides some extra background on the mechanisms behind the throttling.
