1NVIDIA Tegra audio complex 2 3Required properties: 4- compatible : "nvidia,tegra-audio-wm9712" 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 WM9712's pins, and the jacks on the board: 16 17 WM9712 pins: 18 19 * MONOOUT 20 * HPOUTL 21 * HPOUTR 22 * LOUT2 23 * ROUT2 24 * OUT3 25 * LINEINL 26 * LINEINR 27 * PHONE 28 * PCBEEP 29 * MIC1 30 * MIC2 31 * Mic Bias 32 33 Board connectors: 34 35 * Headphone 36 * LineIn 37 * Mic 38 39- nvidia,ac97-controller : The phandle of the Tegra AC97 controller 40 41 42Example: 43 44sound { 45 compatible = "nvidia,tegra-audio-wm9712-colibri_t20", 46 "nvidia,tegra-audio-wm9712"; 47 nvidia,model = "Toradex Colibri T20"; 48 49 nvidia,audio-routing = 50 "Headphone", "HPOUTL", 51 "Headphone", "HPOUTR", 52 "LineIn", "LINEINL", 53 "LineIn", "LINEINR", 54 "Mic", "MIC1"; 55 56 nvidia,ac97-controller = <&ac97>; 57 58 clocks = <&tegra_car 112>, <&tegra_car 113>, <&tegra_car 93>; 59 clock-names = "pll_a", "pll_a_out0", "mclk"; 60}; 61
