From 7168137532d2d27d34811cd5a073ad5c3215b592 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Mon, 10 May 2021 23:25:58 +0300 Subject: [PATCH] ARM: tegra: nexus7: Improve thermal zones Remove unused thermal zone just to clean up device-tree and set critical temperature further apart from the passive cooling trip point since during or thermal testing of Asus Transformer devices we found that CPU could reach the critical temperature in a certain kernel configurations for a brief moment if critical trip point is set close to the passive trip point and then device will be immediately shut off without getting a chance to cool down using passive cooling.
