1 | Broadcom Cygnus IOMUX Controller |
| 2 | ||
| 3 | The Cygnus IOMUX controller supports group based mux configuration. In | |
| 4 | addition, certain pins can be muxed to GPIO function individually. | |
| 5 | ||
| 6 | Required properties: | |
| 7 | ||
| 8 | - compatible: | |
| 9 | Must be "brcm,cygnus-pinmux" | |
| 10 | ||
| 11 | - reg: | |
| 12 | Define the base and range of the I/O address space that contains the Cygnus | |
| 13 | IOMUX registers | |
| 14 | ||
| 15 | Properties in subnodes: | |
| 16 | ||
| 17 | - function: | |
| 18 | The mux function to select | |
| 19 | ||
| 20 | - groups: | |
| 21 | The list of groups to select with a given function | |
| 22 | ||
| 23 | For more details, refer to | |
| 24 | Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt | |
| 25 | ||
| 26 | For example: | |
| 27 | ||
| 4c9847b7 | 28 | pinmux: pinmux@0301d0c8 { |
| 3e16de16 RJ |
29 | compatible = "brcm,cygnus-pinmux"; |
| 30 | reg = <0x0301d0c8 0x1b0>; | |
| 31 | ||
| 32 | pinctrl-names = "default"; | |
| 33 | pinctrl-0 = <&i2s0_default>; | |
| 34 | ||
| 35 | i2s0_default: i2s0_default { | |
| 36 | mux { | |
| 37 | function = "i2s0"; | |
| 38 | groups = "i2s0_0_grp", "i2s0_1_grp"; | |
| 39 | }; | |
