From: Marek Vasut Date: Sat, 2 May 2026 18:55:42 +0000 (+0200) Subject: dt-bindings: clock: renesas,cpg-clocks: Document ZT/ZTR trace clock on R-Mobile APE6 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2abdc3dcf9780d070e55a99fdf8f93440c798b84;p=thirdparty%2Fkernel%2Flinux.git dt-bindings: clock: renesas,cpg-clocks: Document ZT/ZTR trace clock on R-Mobile APE6 Document the ZT trace bus and ZTR trace clocks on R-Mobile APE6. These clocks supply the coresight tracing modules, PTM, TPIU, ETB and replicator. Without these clocks, coresight tracing can not be operated. While this does change the ABI, it does so by extending the existing clock-output-names, therefore if old software is used with new DT, the coresight tracing parts will likely fail to probe, otherwise if new software is used with an old DT, there is no impact.
