From b278838fd29fe0a0561baad23f5d306ca1374919 Mon Sep 17 00:00:00 2001 From: Sumeet R Pawnikar Date: Thu, 30 Jul 2020 09:58:27 +0530 Subject: [PATCH] mb/google/dedede: Update CPU critical temperature Observed thermal shutdown initiated by DPTF due to CPU temperature reaching critical temperature trip value. During stress testing with heavy workload like WebGL Aquarium, sometime CPU temperature spikes till 99 degree Celsius and DPTF initiates system shutdown. This updates CPU critical temperature trip value to 105 degree Celsius to avoid system shutdown.
