title: Cirrus Logic Madera class audio CODECs pinctrl driver
maintainers:
- patches@opensource.cirrus.com
description: |
The Cirrus Logic Madera codecs provide a number of GPIO functions for
interfacing to external hardware and to provide logic outputs to other devices.
Certain groups of GPIO pins also have an alternate function, normally as an
audio interface.
The set of available GPIOs, functions and alternate function groups differs
between CODECs so refer to the datasheet for the CODEC for further information
on what is supported on that device.
The properties for this driver exist within the parent MFD driver node.
See also the core bindings for the parent MFD driver:
Documentation/devicetree/bindings/mfd/cirrus,madera.yaml
And the generic pinmix bindings:
Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
properties:
pinctrl-0:
description:
A phandle to the node containing the subnodes containing default
configurations.
pinctrl-names:
description:
A pinctrl state named "default" must be defined.
const: default
pin-settings:
description:
One subnode is required to contain the default settings. It
contains an arbitrary number of configuration subnodes, one for
each group or pin configuration you want to apply as a default.
