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"; +}; |
