RT5651 audio CODEC This device supports I2C only. Required properties: - compatible : "realtek,rt5651". - reg : The I2C address of the device. Optional properties: - realtek,in2-differential Boolean. Indicate MIC2 input are differential, rather than single-ended. - realtek,dmic-en Boolean. true if dmic is used. - realtek,jack-detect-source u32. Valid values: 1: Use JD1_1 pin for jack-detect 2: Use JD1_2 pin for jack-detect 3: Use JD2 pin for jack-detect - realtek,jack-detect-not-inverted bool. Normal jack-detect switches give an inverted (active-low) signal, set this bool in the rare case you've a jack-detect switch which is not inverted. - realtek,over-current-threshold-microamp u32, micbias over-current detection threshold in µA, valid values are 600, 1500 and 2000µA. - realtek,over-current-scale-factor u32, micbias over-current detection scale-factor, valid values are: 0: Scale current by 0.5 1: Scale current by 0.75 2: Scale current by 1.0 3: Scale current by 1.5 Pins on the device (for linking into audio routes) for RT5651: * DMIC L1 * DMIC R1 * IN1P * IN2P * IN2N * IN3P * HPOL * HPOR * LOUTL * LOUTR * PDML * PDMR Example: rt5651: codec@1a { compatible = "realtek,rt5651"; reg = <0x1a>; realtek,dmic-en = "true"; realtek,in2-diff = "false"; }; |
