title: ASPEED AST2600 Pin Controller

maintainers:
  - Andrew Jeffery <andrew@aj.id.au>

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,ast2600-scu", "syscon", "simple-mfd"

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

  Note: According to the NCSI specification, the reference clock output pin
  (RMIIXRCLKO) is not required on the management controller side. To optimize
  pin usage, add "NCSI" pin groups that are equivalent to the RMII pin groups,
  but without the RMIIXRCLKO pin.
