      1Broadcom Cygnus IOMUX Controller
      2
      3The Cygnus IOMUX controller supports group based mux configuration. In
      4addition, certain pins can be muxed to GPIO function individually.
      5
      6Required 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
     13IOMUX registers
     14
     15Properties 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
     23For more details, refer to
     24Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
     25
     26For example:
     27
     28	pinmux: pinmux@0301d0c8 {
     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			};
     40		};
     41	};
