[PATCH 4/7] arm64: dts: qcom: kodiak: Add label properties to CoreSight devices

Jie Gan
2026-04-10T03:09:33Z

Add label properties to TPDM and CTI nodes in the kodiak 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.
