- 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";
- };
- };
- };
