Improve the binding example by removing all the leading 0x to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
Converted using the following command:
find Documentation/devicetree/bindings -name "*.txt" -exec sed -i -e 's/([^ ])\@0x([0-9a-f])/$1\@$2/g' {} +

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@0301d0c8 {
|
|
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";
|
|
};
|
|
};

};
