It allows the connection of most Cirrus 15*4882a593Smuzhiyun Logic devices on mini-cards, as well as allowing connection of various 16*4882a593Smuzhiyun application processor systems to provide a full evaluation platform. 17*4882a593Smuzhiyun Audio system topology, clocking and power can all be controlled through 18*4882a593Smuzhiyun the Lochnagar, allowing the device under test to be used in a variety of 19*4882a593Smuzhiyun possible use cases. 20*4882a593Smuzhiyun 21*4882a593Smuzhiyun This binding document describes the binding for the audio portion of the 22*4882a593Smuzhiyun driver. 23*4882a593Smuzhiyun 24*4882a593Smuzhiyun This binding must be part of the Lochnagar MFD binding: 25*4882a593Smuzhiyun [1] ../mfd/cirrus,lochnagar.yaml 26*4882a593Smuzhiyun 27*4882a593Smuzhiyunproperties: 28*4882a593Smuzhiyun compatible: 29*4882a593Smuzhiyun enum: 30*4882a593Smuzhiyun - cirrus,lochnagar2-soundcard 31*4882a593Smuzhiyun 32*4882a593Smuzhiyun '#sound-dai-cells': 33*4882a593Smuzhiyun description: 34*4882a593Smuzhiyun The first cell indicating the audio interface. 35*4882a593Smuzhiyun const: 1 36*4882a593Smuzhiyun 37*4882a593Smuzhiyun clocks: 38*4882a593Smuzhiyun description: 39*4882a593Smuzhiyun Master clock source for the sound card, should normally be set to 40*4882a593Smuzhiyun LOCHNAGAR_SOUNDCARD_MCLK provided by the Lochnagar clock driver. 41*4882a593Smuzhiyun maxItems: 1 42*4882a593Smuzhiyun 43*4882a593Smuzhiyun clock-names: 44*4882a593Smuzhiyun const: mclk 45*4882a593Smuzhiyun 46*4882a593Smuzhiyunrequired: 47*4882a593Smuzhiyun - compatible 48*4882a593Smuzhiyun - '#sound-dai-cells' 49*4882a593Smuzhiyun - clocks 50*4882a593Smuzhiyun - clock-names 51*4882a593Smuzhiyun 52*4882a593SmuzhiyunadditionalProperties: false 53
