Subject: [PATCH 2/3] ARM: dts: qcom: pm8841: Add thermal zone config
Date:   Tue, 30 May 2023 01:15:00 +0300
Message-Id: <20230529221501.43455-3-matti.lehtimaki@gmail.com>

Add thermal zone for the PMIC thermal sensor. Temperatures are based on
downstream values, except for critical trip point where 140°C is used
instead of 145°C due to limitations without a configured ADC.
