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

  - compatible: 	Should be one of the following:
  			"aspeed,ast2500-scu", "syscon", "simple-mfd"
  			"aspeed,g5-scu", "syscon", "simple-mfd"

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