[PATCH 2/7] arm64: dts: qcom: talos: Add label properties to CoreSight devices

Jie Gan
2026-04-10T03:09:26Z

Add label properties to CTI and TPDM nodes in the talos device tree to
provide human-readable identifiers for each CoreSight device. These
labels allow userspace tools and the CoreSight framework to identify
devices by name rather than by base address.
