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 clock portion of the |
|
driver. |
