   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
   16   audio interface.
   17 
   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.
   21 
   22   The properties for this driver exist within the parent MFD driver node.
   23 
   24   See also the core bindings for the parent MFD driver:
