1NVIDIA Tegra audio complex 2 3Required properties: 4- compatible : "nvidia,tegra-audio-wm8753" 5- clocks : Must contain an entry for each entry in clock-names. 6 See ../clocks/clock-bindings.txt for details. 7- clock-names : Must include the following entries: 8 - pll_a 9 - pll_a_out0 10 - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk) 11- nvidia,model : The user-visible name of this sound complex. 12- nvidia,audio-routing : A list of the connections between audio components. 13 Each entry is a pair of strings, the first being the connection's sink, 14 the second being the connection's source. Valid names for sources and 15 sinks are the WM8753's pins as documented in the binding for the WM8753, 16 and the jacks on the board: 17 18 * Headphone Jack 19 * Mic Jack 20 21- nvidia,i2s-controller : The phandle of the Tegra I2S1 controller 22- nvidia,audio-codec : The phandle of the WM8753 audio codec 23Example: 24 25sound { 26 compatible = "nvidia,tegra-audio-wm8753-whistler", 27 "nvidia,tegra-audio-wm8753" 28 nvidia,model = "tegra-wm8753-harmony"; 29 30 nvidia,audio-routing = 31 "Headphone Jack", "LOUT1", 32 "Headphone Jack", "ROUT1"; 33 34 nvidia,i2s-controller = <&i2s1>; 35 nvidia,audio-codec = <&wm8753>; 36 37 clocks = <&tegra_car 112>, <&tegra_car 113>, <&tegra_car 93>; 38 clock-names = "pll_a", "pll_a_out0", "mclk"; 39}; 40 41
