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.

2022-12-26arm64: dts: fsd: Update cache propertiesPierre Gondois
The DeviceTree Specification v0.3 specifies that the cache node 'compatible' and 'cache-level' properties are 'required'. Cf. s3.8 Multi-level and Shared Cache Nodes The 'cache-unified' property should be present if one of the properties for unified cache is present ('cache-size', ...). Update the Device Trees accordingly.

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.
