Subject: [PATCH v2] arm64: dts: qcom: pm6150: Add thermal zone for PMIC on-die temperature
Date: Thu, 3 Jun 2021 08:12:34 -0700 [thread overview]
Message-ID: <20210603081215.v2.1.Id4510e9e4baaa3f6c9fdd5cdf4d8606e63c262e3@changeid> (raw)
Add a thermal zone for the pm6150 on-die temperature. The system should
try to shut down orderly when the temperature reaches the critical trip
point at 115°C, otherwise the PMIC will perform a HW power off at 145°C.
Signed-off-by: Matthias Kaehlcke <mka@chromium.org>

Changes in v2:
- remove 'pm6150-' prefix from critical trip point
- updated commit message
