    Subject[PATCH v7 01/23] dt-bindings: ata: ahci-platform: Move dma-coherent to sata-common.yaml
    Date
    Seeing doubtfully any SATA device working without embedded DMA engine
    let's permit the device nodes being equipped with the dma-coherent
    property in case if the platform is capable of cache-coherent DMAs.

    As a side-effect we can drop the explicit dma-coherent property definition
    from the particular device schemas. Currently it concerns the Broadcom
    SATA AHCI controller only.

    Changelog v2:
    - This is a new patch created after rebasing v1 onto the 5.18-rc3 kernel.

    Changelog v4:
    - Move the dma-coherent property to the sata-common.yaml schema instead
    of removing it.
    - Remove the Hannes' rb tag.
