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