It allows the connection of most Cirrus 15 Logic devices on mini-cards, as well as allowing connection of various 16 application processor systems to provide a full evaluation platform. 17 Audio system topology, clocking and power can all be controlled through 18 the Lochnagar, allowing the device under test to be used in a variety of 19 possible use cases. 20 21 This binding document describes the binding for the audio portion of the 22 driver. 23 24 This binding must be part of the Lochnagar MFD binding: 25 [1] ../mfd/cirrus,lochnagar.yaml 26 27properties: 28 compatible: 29 enum: 30 - cirrus,lochnagar2-soundcard 31 32 '#sound-dai-cells': 33 description: 34 The first cell indicating the audio interface. 35 const: 1 36 37 clocks: 38 description: 39 Master clock source for the sound card, should normally be set to 40 LOCHNAGAR_SOUNDCARD_MCLK provided by the Lochnagar clock driver. 41 maxItems: 1 42 43 clock-names: 44 const: mclk 45 46required: 47 - compatible 48 - '#sound-dai-cells' 49 - clocks 50 - clock-names 51 52additionalProperties: false 53
