From ba5487acf47b3d9a8e36ec8538659bb7eb8cf7a1 Mon Sep 17 00:00:00 2001 From: Duncan Laurie <dlaurie@chromium.org> Date: Thu, 22 Oct 2015 10:53:01 -0700 Subject: google/chell: Set DPTF critical temperature to 99C If we boot without a heatsink then DPTF may power off the system when it starts if the CPU temp is >90C. Since TJmax is 100C set the critical threshold to just below that value. Also remove the active thresholds as chell does not have a fan. This will have DPTF use the default values but without the DPTF active policy it shouldn't get used.
