[PATCH 0/7] arm64: dts: qcom: Add label properties to CoreSight devices

The CoreSight framework and userspace tools identify trace devices by
their base address, which is not human-readable. The label property
provides a stable, descriptive name for each TPDM and CTI device,
allowing tools to refer to devices by name rather than address.

This series adds label properties to TPDM and CTI nodes across seven
Qualcomm platforms:
lemans
talos
monaco
kodiak
kaanapali
sm8750
hamoa

With the change, we will have a sysfs node for each Coresight device:
root@qemuarm64:/sys/bus/coresight/devices/tpdm0# cat label
tpdm_spdm
