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

26 For 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 };
