1RT5682 audio CODEC 2 3This device supports I2C only. 4 5Required properties: 6 7- compatible : "realtek,rt5682" or "realtek,rt5682i" 8 9- reg : The I2C address of the device. 10 11- AVDD-supply: phandle to the regulator supplying analog power through the 12 AVDD pin 13 14- MICVDD-supply: phandle to the regulator supplying power for the microphone 15 bias through the MICVDD pin. Either MICVDD or VBAT should be present. 16 17- VBAT-supply: phandle to the regulator supplying battery power through the 18 VBAT pin. Either MICVDD or VBAT should be present. 19 20- DBVDD-supply: phandle to the regulator supplying I/O power through the DBVDD 21 pin. 22 23- LDO1-IN-supply: phandle to the regulator supplying power to the digital core 24 and charge pump through the LDO1_IN pin. 25 26Optional properties: 27 28- interrupts : The CODEC's interrupt output. 29 30- realtek,dmic1-data-pin 31 0: dmic1 is not used 32 1: using GPIO2 pin as dmic1 data pin 33 2: using GPIO5 pin as dmic1 data pin 34 35- realtek,dmic1-clk-pin 36 0: using GPIO1 pin as dmic1 clock pin 37 1: using GPIO3 pin as dmic1 clock pin 38 39- realtek,jd-src 40 0: No JD is used 41 1: using JD1 as JD source 42 43- realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. 44 45- realtek,btndet-delay 46 The debounce delay for push button. 47 The delay time is realtek,btndet-delay value multiple of 8.192 ms. 48 If absent, the default is 16. 49 50- #clock-cells : Should be set to '<1>', wclk and bclk sources provided. 51- clock-output-names : Name given for DAI clocks output. 52 53- clocks : phandle and clock specifier for codec MCLK. 54- clock-names : Clock name string for 'clocks' attribute, should be "mclk". 55 56- realtek,dmic-clk-rate-hz : Set the clock rate (hz) for the requirement of 57 the particular DMIC. 58 59- realtek,dmic-delay-ms : Set the delay time (ms) for the requirement of 60 the particular DMIC. 61 62- realtek,dmic-clk-driving-high : Set the high driving of the DMIC clock out. 63 64- #sound-dai-cells: Should be set to '<1>'. 65 66Pins on the device (for linking into audio routes) for RT5682: 67 68 * DMIC L1 69 * DMIC R1 70 * IN1P 71 * HPOL 72 * HPOR 73 74Example: 75 76rt5682 { 77 compatible = "realtek,rt5682i"; 78 reg = <0x1a>; 79 interrupt-parent = <&gpio>; 80 interrupts = <TEGRA_GPIO(U, 6) IRQ_TYPE_LEVEL_HIGH>; 81 realtek,ldo1-en-gpios = 82 <&gpio TEGRA_GPIO(R, 2) GPIO_ACTIVE_HIGH>; 83 realtek,dmic1-data-pin = <1>; 84 realtek,dmic1-clk-pin = <1>; 85 realtek,jd-src = <1>; 86 realtek,btndet-delay = <16>; 87 88 #clock-cells = <1>; 89 clock-output-names = "rt5682-dai-wclk", "rt5682-dai-bclk"; 90 91 clocks = <&osc>; 92 clock-names = "mclk"; 93 94 AVDD-supply = <&avdd_reg>; 95 MICVDD-supply = <&micvdd_reg>; 96 DBVDD-supply = <&dbvdd_reg>; 97 LDO1-IN-supply = <&ldo1_in_reg>; 98}; 99
