Subject: [PATCH v5 08/10] arm64: dts: lx2160a: add labels to thermal trip-point nodes
Date: Sun, 10 May 2026 17:12:10 +0200	[thread overview]
Message-ID: <20260510-lx2160-pci-v5-8-540b83852227@solid-run.com> (raw)
In-Reply-To: <20260510-lx2160-pci-v5-0-540b83852227@solid-run.com>

LX2160A SoC dtsi defines rather conservative thermal trip points,
alert at 85°C and critical at 95°C.

This is okay for most boards, however the SoC maximum junction
temperature is 105°C in both commercial and industrial version.

Industrial grade boards need to change the thresholds to avoid premature
thermal shutdown in high-temeprature environments.

Add labels to all thermal trip point nodes, enabling board dts to
reference them and modify properties.
