|
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.
|
|
|
|

each group or pin configuration you want to apply as a default.
