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.
