+
+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 audio portion of the
+ driver.
+
+ This binding must be part of the Lochnagar MFD binding:
