+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
