| description: | |
| Lochnagar is an evaluation and development board for Cirrus Logic |
| Smart CODEC and Amp devices. It allows the connection of most Cirrus |
| Logic devices on mini-cards, as well as allowing connection of various |
| application processor systems to provide a full evaluation platform. |
| Audio system topology, clocking and power can all be controlled through |
| the Lochnagar, allowing the device under test to be used in a variety of |
| possible use cases. |
| |
| This binding document describes the binding for the pinctrl portion of |
| the driver. |
| |
| Also see these documents for generic binding information: |
| [1] GPIO : ../gpio/gpio.txt |
| [2] Pinctrl: ../pinctrl/pinctrl-bindings.txt |
| |
| And these for relevant defines: |
| [3] include/dt-bindings/pinctrl/lochnagar.h |

| This binding must be part of the Lochnagar MFD binding: |
