|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
|
|
|
|
|
