It allows the connection of most Cirrus 15*e1bfa75dSCharles Keepax Logic devices on mini-cards, as well as allowing connection of various 16*e1bfa75dSCharles Keepax application processor systems to provide a full evaluation platform. 17*e1bfa75dSCharles Keepax Audio system topology, clocking and power can all be controlled through 18*e1bfa75dSCharles Keepax the Lochnagar, allowing the device under test to be used in a variety of 19*e1bfa75dSCharles Keepax possible use cases. 20*e1bfa75dSCharles Keepax 21*e1bfa75dSCharles Keepax This binding document describes the binding for the audio portion of the 22*e1bfa75dSCharles Keepax driver. 23*e1bfa75dSCharles Keepax 24*e1bfa75dSCharles Keepax This binding must be part of the Lochnagar MFD binding: 25*e1bfa75dSCharles Keepax [1] ../mfd/cirrus,lochnagar.yaml 26*e1bfa75dSCharles Keepax 27*e1bfa75dSCharles Keepaxproperties: 28*e1bfa75dSCharles Keepax compatible: 29*e1bfa75dSCharles Keepax enum: 30*e1bfa75dSCharles Keepax - cirrus,lochnagar2-soundcard 31*e1bfa75dSCharles Keepax 32*e1bfa75dSCharles Keepax '#sound-dai-cells': 33*e1bfa75dSCharles Keepax description: 34*e1bfa75dSCharles Keepax The first cell indicating the audio interface. 35*e1bfa75dSCharles Keepax const: 1 36*e1bfa75dSCharles Keepax 37*e1bfa75dSCharles Keepax clocks: 38*e1bfa75dSCharles Keepax description: 39*e1bfa75dSCharles Keepax Master clock source for the sound card, should normally be set to 40*e1bfa75dSCharles Keepax LOCHNAGAR_SOUNDCARD_MCLK provided by the Lochnagar clock driver. 41*e1bfa75dSCharles Keepax maxItems: 1 42*e1bfa75dSCharles Keepax 43*e1bfa75dSCharles Keepax clock-names: 44*e1bfa75dSCharles Keepax const: mclk 45*e1bfa75dSCharles Keepax 46*e1bfa75dSCharles Keepaxrequired: 47*e1bfa75dSCharles Keepax - compatible 48*e1bfa75dSCharles Keepax - '#sound-dai-cells' 49*e1bfa75dSCharles Keepax - clocks 50*e1bfa75dSCharles Keepax - clock-names 51*e1bfa75dSCharles Keepax 52*e1bfa75dSCharles KeepaxadditionalProperties: false 53
