+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

+ description:

+ contains an arbitrary number of configuration subnodes, one for
+ each group or pin configuration you want to apply as a default.
