[PATCH v3 3/4] ARM: dts: renesas: r8a7740: Add ZT/ZTR trace clock on R-Mobile A1
From: Marek Vasut
Date: Wed Apr 22 2026 - 19:38:26 EST
Add ZT trace bus and ZTR trace clock on the R-Mobile A1.
These clock supply the coresight tracing modules, PTM, TPIU,
ETB and replicator. Without these clock, the coresight tracing
can not be operated.
