| 2 | ---------------------- |
| 3 | |
| 4 | The Aspeed SoCs vary in functionality inside a generation but have a common mux |
| 5 | device register layout. |
| 6 | |
| 7 | Required properties: |
| 8 | - compatible : Should be any one of the following: |
| 9 | "aspeed,ast2400-pinctrl" |
| 10 | "aspeed,g4-pinctrl" |
| 11 | "aspeed,ast2500-pinctrl" |
| 12 | "aspeed,g5-pinctrl" |
| 13 | |
| 14 | The pin controller node should be a child of a syscon node with the required |
| 15 | property: |
| 16 | - compatible: "syscon", "simple-mfd" |
| 17 | |
| 18 | Refer to the the bindings described in |
| 19 | Documentation/devicetree/bindings/mfd/syscon.txt |
| 20 | |
| 21 | Subnode Format |
| 22 | -------------- |
| 23 | |
| 24 | The required properties of child nodes are (as defined in pinctrl-bindings): |
| 25 | - function |
| 26 | - groups |
| 27 | |
| 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 |
| 30 | supported: |
| 31 | |
| 32 | aspeed,ast2400-pinctrl, aspeed,g4-pinctrl: |
