  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.
