title: Cirrus Logic Lochnagar Audio Development Board

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:
[4] ../mfd/cirrus,lochnagar.yaml
