| Aspeed Pin Controllers |
| ---------------------- |
| |
| The Aspeed SoCs vary in functionality inside a generation but have a common mux |
| device register layout. |
| |
| Required properties: |
| - compatible : Should be any one of the following: |
| "aspeed,ast2400-pinctrl" |
| "aspeed,g4-pinctrl" |
| "aspeed,ast2500-pinctrl" |
| "aspeed,g5-pinctrl" |
| |
| The pin controller node should be a child of a syscon node with the required |
| property: |
| - compatible: "syscon", "simple-mfd" |
| |
| Refer to the the bindings described in |
| Documentation/devicetree/bindings/mfd/syscon.txt |
| |
| Subnode Format |
| -------------- |
| |
| The required properties of child nodes are (as defined in pinctrl-bindings): |
| - function |
| - groups |
| |
| Each function has only one associated pin group. Each group is named by its |
| function. The following values for the function and groups properties are |
| supported: |
| |
| aspeed,ast2400-pinctrl, aspeed,g4-pinctrl: |
