RT5650/RT5645 audio CODEC This device supports I2C only. Required properties: - compatible : One of "realtek,rt5645" or "realtek,rt5650". - reg : The I2C address of the device. - interrupts : The CODEC's interrupt output. Optional properties: - hp-detect-gpios: a GPIO spec for the external headphone detect pin. If jd-mode = 0, we will get the JD status by getting the value of hp-detect-gpios. - realtek,in2-differential Boolean. Indicate MIC2 input are differential, rather than single-ended. - realtek,dmic1-data-pin 0: dmic1 is not used 1: using IN2P pin as dmic1 data pin 2: using GPIO6 pin as dmic1 data pin 3: using GPIO10 pin as dmic1 data pin 4: using GPIO12 pin as dmic1 data pin - realtek,dmic2-data-pin 0: dmic2 is not used 1: using IN2N pin as dmic2 data pin 2: using GPIO5 pin as dmic2 data pin 3: using GPIO11 pin as dmic2 data pin -- realtek,jd-mode : The JD mode of rt5645/rt5650 0 : rt5645/rt5650 JD function is not used 1 : Mode-0 (VDD=3.3V), two port jack detection 2 : Mode-1 (VDD=3.3V), one port jack detection 3 : Mode-2 (VDD=1.8V), one port jack detection Pins on the device (for linking into audio routes) for RT5645/RT5650: * DMIC L1 * DMIC R1 * DMIC L2 * DMIC R2 * IN1P * IN1N * IN2P * IN2N * Haptic Generator * HPOL * HPOR * LOUTL * LOUTR * PDM1L * PDM1R * SPOL * SPOR Example: codec: rt5650@1a { compatible = "realtek,rt5650"; reg = <0x1a>; hp-detect-gpios = <&gpio 19 0>; interrupt-parent = <&gpio>; interrupts = <7 IRQ_TYPE_EDGE_FALLING>; realtek,dmic-en = "true"; realtek,en-jd-func = "true"; realtek,jd-mode = <3>; };
