From: Robin Murphy Date: Wed, 4 Sep 2024 17:34:02 +0000 (+0100) Subject: dt-bindings/perf: Add Arm NI-700 PMU X-Git-Tag: v6.12-rc1~221^2~4^2~4 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=abbe74dd105b45330dd269530060d30441d45b95;p=thirdparty%2Flinux.git dt-bindings/perf: Add Arm NI-700 PMU Add an initial binding for the Arm NI-700 interconnect PMU. As with the Arm CMN family, there are already future NI products on the roadmap, so the overall binding is named generically just in case any non-discoverable incompatibility between generations crops up.
