From dc6071d2ce22d8ed0bd92162484e864dadace87a Mon Sep 17 00:00:00 2001 From: Wisley Chen Date: Tue, 11 Jan 2022 18:07:20 +0600 Subject: [PATCH] mb/google/brya/var/redrix{4es}: Set tcc_offset value to 3 The redrix thermal team has determined that the TCC circuit trip temperature should be set to 97C, therefore, because the offset is subtracted from 100C, set the `tcc_offset` register in the devicetree to 3.
