Subject[PATCH v2] arm64: dts: qcom: pm6150: Add thermal zone for PMIC on-die temperature
Date
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
