-Cirrus Logic Lochnagar Audio Development Board
-
-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:
- [4] ../mfd/cirrus,lochnagar.txt
-
-Required properties:
-
- - compatible : One of the following strings:
- "cirrus,lochnagar2-soundcard"
-
- - #sound-dai-cells : Must be set to 1.
-
- - clocks : Contains an entry for each entry in clock-names.
- - clock-names : Must include the following clocks:
- "mclk" Master clock source for the sound card, should normally
- be set to LOCHNAGAR_SOUNDCARD_MCLK provided by the Lochnagar
- clock driver.
-
-Example:
-
-lochnagar-sc {
- compatible = "cirrus,lochnagar2-soundcard";
-
- #sound-dai-cells = <1>;
-
- clocks = <&lochnagar_clk LOCHNAGAR_SOUNDCARD_MCLK>;
- clock-names = "mclk";
-};
