Indicate MIC2 input are differential, rather than single-ended.15 16- realtek,dmic-en17 Boolean. true if dmic is used.18 19- realtek,jack-detect-source20 u32. Valid values:21 1: Use JD1_1 pin for jack-detect22 2: Use JD1_2 pin for jack-detect23 3: Use JD2 pin for jack-detect24 25- realtek,jack-detect-not-inverted26 bool. Normal jack-detect switches give an inverted (active-low) signal,27 set this bool in the rare case you've a jack-detect switch which is not28 inverted.29 30- realtek,over-current-threshold-microamp31 u32, micbias over-current detection threshold in µA, valid values are32 600, 1500 and 2000µA.33 34- realtek,over-current-scale-factor35 u32, micbias over-current detection scale-factor, valid values are:36 0: Scale current by 0.537 1: Scale current by 0.7538 2: Scale current by 1.039 3: Scale current by 1.540 41Pins on the device (for linking into audio routes) for RT5651:42 43 * DMIC L144 * DMIC R145 * IN1P46 * IN2P47 * IN2N48 * IN3P49 * HPOL50 * HPOR51 * LOUTL52 * LOUTR53 * PDML54 * PDMR55 56Example:57 58rt5651: codec@1a {59 compatible = "realtek,rt5651";60 reg = <0x1a>;61 realtek,dmic-en = "true";62 realtek,in2-diff = "false";63};64
