12 description: |+
13 The pin controller node should be the child of a syscon node with the
14 required property:
15
16 - compatible: Should be one of the following:
17 "aspeed,ast2600-scu", "syscon", "simple-mfd"
18
19 Refer to the bindings described in
20 Documentation/devicetree/bindings/mfd/syscon.yaml
21
22 Note: According to the NCSI specification, the reference clock output pin
23 (RMIIXRCLKO) is not required on the management controller side. To optimize
24 pin usage, add "NCSI" pin groups that are equivalent to the RMII pin groups,
25 but without the RMIIXRCLKO pin.
