[PATCH 1/2] arm64: dts: qcom: msm8937: Fix CPU4 thermal trip point type
From: Krzysztof Kozlowski
Date: Fri Nov 06 2026 - 12:37:41 EST
CPU4 thermal zone, unlike the rest CPU5-7, has reversed types for
75 and 85 *C trips: the "passive", not "hot" should be used for alert
triggering cooling device. Wrong types could cause missing thermal
throttling of CPU4.
