dt-bindings: perf: fsl-imx-ddr: Add compatible string for i.MX8QM, i.MX8QXP and i.MX8DXL

2025-11-24T15:39:05+00:00

Add compatible string fsl,imx8qm-ddr-pmu, fsl,imx8qxp-ddr-pmu, which fallback to fsl,imx8-ddr-pmu and fsl,imx8dxl-db-pmu (for data bus fabric). Add clocks, clock-names for fsl,imx8dxl-db-pmu and keep the same restriction for existing compatible strings. Reviewed-by: Rob Herring (Arm) Signed-off-by: Frank Li Signed-off-by: Will Deacon

dt-bindings/perf: Add Arm NI-700 PMU

2024-09-06T11:58:28+00:00

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.

dt-bindings: perf: arm-cmn: Add CMN S3

2024-09-04T15:04:08+00:00

The CMN S3 PMU is functionally still very similar to CMN-700, however while the register contents are compatible, many of them are moved to different offsets. While this is technically discoverable by a careful driver that understands the part number in the peripheral ID registers (which do at least remain in the same place), a new unique compatible seems warranted to avoid any surprises.

dt-bindings/perf: Add Arm CoreSight PMU

2024-02-09T17:34:35+00:00

Add a binding for implementations of the Arm CoreSight Performance Monitoring Unit Architecture. Not to be confused with CoreSight debug and trace, the PMU architecture defines a standard MMIO interface for event counters following a similar design to the CPU PMU architecture, where the implementation and most of its features are discoverable through ID registers.
