    Subject[RFC PATCH devicetree 03/10] dt-bindings: ls-extirq: replace "interrupt-map" documentation with "fsl,extirq-map"
    Date
    This change does 3 things at once:
    - documents the recently added "fsl,extirq-map" property, which replaces
    "interrupt-map"
    - clarifies the format of the property whose name is changing
    - hides the "interrupt-map" property, that the driver still supports for
    backwards compatibility reasons, although not for long.
