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