Subject: [PATCH] arm64: dts: qcom: ipq8074: add critical thermal trips
Date:   Wed,  7 Jun 2023 20:44:48 +0200
Message-Id: <20230607184448.2512179-1-robimarko@gmail.com>

According to bindings, thermal zones must have associated trips as well.
Since we currently dont have CPUFreq support and thus no passive cooling
lets start by defining critical trips to protect the devices against
severe overheating.
