2024-04-29arm/arm64: dts: Drop "arm,armv8-pmuv3" compatible usageRob Herring
The "arm,armv8-pmuv3" compatible is intended only for s/w models. Primarily, it doesn't provide any detail on uarch specific events. There's still remaining cases for CPUs without any corresponding PMU definition and for big.LITTLE systems which only have a single PMU node (there should be one per core type).

2023-12-07arm64: dts: fsd: add specific compatibles for Tesla FSDKrzysztof Kozlowski
Tesla FSD is a derivative of Samsung Exynos SoC, thus just like the others it reuses several devices from older designs. Historically we kept the old (block's) compatible only. This works fine and there is no bug here, however guidelines expressed in Documentation/devicetree/bindings/writing-bindings.rst state that: 1. Compatibles should be specific. 2. We should add new compatibles in case of bugs or features. Add Tesla FSD compatible specific to be used with an existing fallback. This will also help reviews of new code using existing DTS as template. No functional impact on Linux drivers behavior.

2022-05-04arm64: dts: fsd: drop useless 'dma-channels/requests' propertiesKrzysztof Kozlowski
The pl330 DMA controller provides number of DMA channels and requests through its registers, so duplicating this information (with a chance of mistakes) in DTS is pointless. Additionally the DTS used always wrong property names which causes DT schema check failures - the bindings documented 'dma-channels' and 'dma-requests' properties without leading hash sign.
