1RT5677 audio CODEC 2 3This device supports I2C only. 4 5Required properties: 6 7- compatible : "realtek,rt5677". 8 9- reg : The I2C address of the device. 10 11- interrupts : The CODEC's interrupt output. 12 13- gpio-controller : Indicates this device is a GPIO controller. 14 15- #gpio-cells : Should be two. The first cell is the pin number and the 16 second cell is used to specify optional parameters (currently unused). 17 18Optional properties: 19 20- realtek,pow-ldo2-gpio : The GPIO that controls the CODEC's POW_LDO2 pin. 21 22- realtek,in1-differential 23- realtek,in2-differential 24- realtek,lout1-differential 25- realtek,lout2-differential 26- realtek,lout3-differential 27 Boolean. Indicate MIC1/2 input and LOUT1/2/3 outputs are differential, 28 rather than single-ended. 29 30Pins on the device (for linking into audio routes): 31 32 * IN1P 33 * IN1N 34 * IN2P 35 * IN2N 36 * MICBIAS1 37 * DMIC1 38 * DMIC2 39 * DMIC3 40 * DMIC4 41 * LOUT1 42 * LOUT2 43 * LOUT3 44 45Example: 46 47rt5677 { 48 compatible = "realtek,rt5677"; 49 reg = <0x2c>; 50 interrupt-parent = <&gpio>; 51 interrupts = <TEGRA_GPIO(W, 3) GPIO_ACTIVE_HIGH>; 52 53 gpio-controller; 54 #gpio-cells = <2>; 55 56 realtek,pow-ldo2-gpio = 57 <&gpio TEGRA_GPIO(V, 3) GPIO_ACTIVE_HIGH>; 58 realtek,in1-differential = "true"; 59}; 60
