1 Broadcom Cygnus IOMUX Controller
3 The Cygnus IOMUX controller supports group based mux configuration. In
4 addition, certain pins can be muxed to GPIO function individually.
9 Must be "brcm,cygnus-pinmux"
12 Define the base and range of the I/O address space that contains the Cygnus
15 Properties in subnodes:
18 The mux function to select
21 The list of groups to select with a given function
