compatible: "nxp,s32-siul2-eirq"

  filter-prescaler:
    type: int
    description: |
      Setting the prescaler which selects the clock for all digital filters.
      Valid range: 0 - 15.

  interrupt-names:
    description: |
      For platforms that external interrupt lines belong to different interrupt
      IDs (i.e. there is no single interrupt handler for all the lines), this
      property is used by the shim driver to determine the ISR name as defined
      by the HAL.

      The naming must follow: <from-line-number>_<to-line-number>, for example:
      interrupt-names = "0_7", "8_15", "16_23", "24_31";

child-binding:
  description: |
    NXP S32 SIUL2 External Interrupt line configuration. For each
    interrupt line that has specific requirements about digital
    glitch filter, a node using this binding must be added, the
    name must be "line_<line_number>". For example:

      line_0: line_0 {
          filter-enable;
          filter-counter = <5>;
      };

    If the controller has no child node, the digital filter will be
    disabled for all external interrupt lines.

  properties:
    filter-enable:
      type: boolean
      required: true
      description: |
        Enable digital glitch filter to filter out glitches on the input pad.

    filter-counter:
      type: int
      required: true
      description: |
        Configuring the filter counter associated with digital glitch filter.
        Valid range: 0 - 15.
