    Subject[PATCH 3/5] dt-bindings: firmware: qcom-scm: Add optional interrupt
    Date
    Add an interrupt specification to the bindings to support the wait-queue
    feature.

    There's a patch already in flight [1] to convert the bindings to YAML. I
    will make a patch against it when it gets accepted.
