| Broadcom Cygnus IOMUX Controller |
| |
| The Cygnus IOMUX controller supports group based mux configuration. In |
| addition, certain pins can be muxed to GPIO function individually. |
| |
| Required properties: |
| |
| - compatible: |
| Must be "brcm,cygnus-pinmux" |
| |
| - reg: |
| Define the base and range of the I/O address space that contains the Cygnus |
| IOMUX registers |
| |
| Properties in subnodes: |
| |
| - function: |
| The mux function to select |
| |
| - groups: |
| The list of groups to select with a given function |
| |
| For more details, refer to |
| Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt |
| |
| For example: |
| |
| pinmux: pinmux@0x0301d0c8 { |
| compatible = "brcm,cygnus-pinmux"; |
| reg = <0x0301d0c8 0x1b0>; |
| |
| pinctrl-names = "default"; |
| pinctrl-0 = <&i2s0_default>; |
| |
| i2s0_default: i2s0_default { |
| mux { |
| function = "i2s0"; |
| groups = "i2s0_0_grp", "i2s0_1_grp"; |
| }; |
| }; |
| }; |
