1*c66ec88fSEmmanuel VadotNVIDIA Tegra audio complex, with RT5640 CODEC 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotRequired properties: 4*c66ec88fSEmmanuel Vadot- compatible : "nvidia,tegra-audio-rt5640" 5*c66ec88fSEmmanuel Vadot- clocks : Must contain an entry for each entry in clock-names. 6*c66ec88fSEmmanuel Vadot See ../clocks/clock-bindings.txt for details. 7*c66ec88fSEmmanuel Vadot- clock-names : Must include the following entries: 8*c66ec88fSEmmanuel Vadot - pll_a 9*c66ec88fSEmmanuel Vadot - pll_a_out0 10*c66ec88fSEmmanuel Vadot - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk) 11*c66ec88fSEmmanuel Vadot- nvidia,model : The user-visible name of this sound complex. 12*c66ec88fSEmmanuel Vadot- nvidia,audio-routing : A list of the connections between audio components. 13*c66ec88fSEmmanuel Vadot Each entry is a pair of strings, the first being the connection's sink, 14*c66ec88fSEmmanuel Vadot the second being the connection's source. Valid names for sources and 15*c66ec88fSEmmanuel Vadot sinks are the RT5640's pins (as documented in its binding), and the jacks 16*c66ec88fSEmmanuel Vadot on the board: 17*c66ec88fSEmmanuel Vadot 18*c66ec88fSEmmanuel Vadot * Headphones 19*c66ec88fSEmmanuel Vadot * Speakers 20*c66ec88fSEmmanuel Vadot * Mic Jack 21*c66ec88fSEmmanuel Vadot 22*c66ec88fSEmmanuel Vadot- nvidia,i2s-controller : The phandle of the Tegra I2S controller that's 23*c66ec88fSEmmanuel Vadot connected to the CODEC. 24*c66ec88fSEmmanuel Vadot- nvidia,audio-codec : The phandle of the RT5640 audio codec. This binding 25*c66ec88fSEmmanuel Vadot assumes that AIF1 on the CODEC is connected to Tegra. 26*c66ec88fSEmmanuel Vadot 27*c66ec88fSEmmanuel VadotOptional properties: 28*c66ec88fSEmmanuel Vadot- nvidia,hp-det-gpios : The GPIO that detects headphones are plugged in 29*c66ec88fSEmmanuel Vadot 30*c66ec88fSEmmanuel VadotExample: 31*c66ec88fSEmmanuel Vadot 32*c66ec88fSEmmanuel Vadotsound { 33*c66ec88fSEmmanuel Vadot compatible = "nvidia,tegra-audio-rt5640-dalmore", 34*c66ec88fSEmmanuel Vadot "nvidia,tegra-audio-rt5640"; 35*c66ec88fSEmmanuel Vadot nvidia,model = "NVIDIA Tegra Dalmore"; 36*c66ec88fSEmmanuel Vadot 37*c66ec88fSEmmanuel Vadot nvidia,audio-routing = 38*c66ec88fSEmmanuel Vadot "Headphones", "HPOR", 39*c66ec88fSEmmanuel Vadot "Headphones", "HPOL", 40*c66ec88fSEmmanuel Vadot "Speakers", "SPORP", 41*c66ec88fSEmmanuel Vadot "Speakers", "SPORN", 42*c66ec88fSEmmanuel Vadot "Speakers", "SPOLP", 43*c66ec88fSEmmanuel Vadot "Speakers", "SPOLN"; 44*c66ec88fSEmmanuel Vadot 45*c66ec88fSEmmanuel Vadot nvidia,i2s-controller = <&tegra_i2s1>; 46*c66ec88fSEmmanuel Vadot nvidia,audio-codec = <&rt5640>; 47*c66ec88fSEmmanuel Vadot 48*c66ec88fSEmmanuel Vadot nvidia,hp-det-gpios = <&gpio 143 0>; /* GPIO PR7 */ 49*c66ec88fSEmmanuel Vadot 50*c66ec88fSEmmanuel Vadot clocks = <&tegra_car 216>, <&tegra_car 217>, <&tegra_car 120>; 51*c66ec88fSEmmanuel Vadot clock-names = "pll_a", "pll_a_out0", "mclk"; 52*c66ec88fSEmmanuel Vadot}; 53
