1RT5650/RT5645 audio CODEC 2 3This device supports I2C only. 4 5Required properties: 6 7- compatible : One of "realtek,rt5645" or "realtek,rt5650". 8 9- reg : The I2C address of the device. 10 11- interrupts : The CODEC's interrupt output. 12 13- avdd-supply: Power supply for AVDD, providing 1.8V. 14 15- cpvdd-supply: Power supply for CPVDD, providing 3.5V. 16 17Optional properties: 18 19- hp-detect-gpios: 20 a GPIO spec for the external headphone detect pin. If jd-mode = 0, 21 we will get the JD status by getting the value of hp-detect-gpios. 22 23- realtek,in2-differential 24 Boolean. Indicate MIC2 input are differential, rather than single-ended. 25 26- realtek,dmic1-data-pin 27 0: dmic1 is not used 28 1: using IN2P pin as dmic1 data pin 29 2: using GPIO6 pin as dmic1 data pin 30 3: using GPIO10 pin as dmic1 data pin 31 4: using GPIO12 pin as dmic1 data pin 32 33- realtek,dmic2-data-pin 34 0: dmic2 is not used 35 1: using IN2N pin as dmic2 data pin 36 2: using GPIO5 pin as dmic2 data pin 37 3: using GPIO11 pin as dmic2 data pin 38 39-- realtek,jd-mode : The JD mode of rt5645/rt5650 40 0 : rt5645/rt5650 JD function is not used 41 1 : Mode-0 (VDD=3.3V), two port jack detection 42 2 : Mode-1 (VDD=3.3V), one port jack detection 43 3 : Mode-2 (VDD=1.8V), one port jack detection 44 45Pins on the device (for linking into audio routes) for RT5645/RT5650: 46 47 * DMIC L1 48 * DMIC R1 49 * DMIC L2 50 * DMIC R2 51 * IN1P 52 * IN1N 53 * IN2P 54 * IN2N 55 * Haptic Generator 56 * HPOL 57 * HPOR 58 * LOUTL 59 * LOUTR 60 * PDM1L 61 * PDM1R 62 * SPOL 63 * SPOR 64 65Example: 66 67codec: rt5650@1a { 68 compatible = "realtek,rt5650"; 69 reg = <0x1a>; 70 hp-detect-gpios = <&gpio 19 0>; 71 interrupt-parent = <&gpio>; 72 interrupts = <7 IRQ_TYPE_EDGE_FALLING>; 73 realtek,dmic-en = "true"; 74 realtek,en-jd-func = "true"; 75 realtek,jd-mode = <3>; 76};
