    Subject[PATCH net-next v5 1/9] dt-bindings: net: Expand pcs-handle to an array
    Date
    This allows multiple phandles to be specified for pcs-handle, such as
    when multiple PCSs are present for a single MAC. To differentiate
    between them, also add a pcs-handle-names property.

    This was previously submitted as [1]. I expect to update this series
    more, so I have moved it here. Changes from that version include:
    - Add maxItems to existing bindings
    - Add a dependency from pcs-names to pcs-handle.

    (no changes since v4)

    Changes in v4:
    - Use pcs-handle-names instead of pcs-names, as discussed

    Changes in v3:
    - New
