4 The Aspeed SoCs vary in functionality inside a generation but have a common mux
5 device register layout.
8 - compatible : Should be any one of the following:
9 "aspeed,ast2400-pinctrl"
11 "aspeed,ast2500-pinctrl"
14 The pin controller node should be a child of a syscon node with the required
16 - compatible: "syscon", "simple-mfd"
18 Refer to the the bindings described in
19 Documentation/devicetree/bindings/mfd/syscon.txt
24 The required properties of child nodes are (as defined in pinctrl-bindings):
28 Each function has only one associated pin group. Each group is named by its
29 function. The following values for the function and groups properties are
