From 39f9fbc57aeb60e65ec42d370d7ab76c0a4584d6 Mon Sep 17 00:00:00 2001 From: Sumeet Pawnikar Date: Wed, 27 Mar 2019 14:16:01 +0530 Subject: mb/mainboard/google/hatch/variants: Set tcc_offset value Set tcc_offset value to 10C. It configures the Thermal Control Circuit (TCC) activation value to 90C. This prevents any abrupt thermal shutdown by taking early thermal throttling action when CPU temperature goes above 90C.
