| 12 | description: | |
| 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: |
