description: |+
  The pin controller node should be the child of a syscon node with the
  required property:

  - compatible:     Should be one of the following:
                    "aspeed,ast2400-scu", "syscon", "simple-mfd"

  Refer to the the bindings described in
  Documentation/devicetree/bindings/mfd/syscon.yaml
