| 2 | |
| 3 | This device supports I2C only. |
| 4 | |
| 5 | Required properties: |
| 6 | |
| 7 | - compatible : "realtek,rt5651". |
| 8 | |
| 9 | - reg : The I2C address of the device. |
| 10 | |
| 11 | Optional properties: |
| 12 | |
| 13 | - realtek,in2-differential |
| 14 | Boolean. Indicate MIC2 input are differential, rather than single-ended. |
| 15 | |
| 16 | - realtek,dmic-en |
| 17 | Boolean. true if dmic is used. |
| 18 | |
| 19 | - realtek,jack-detect-source |
| 20 | u32. Valid values: |
| 21 | 1: Use JD1_1 pin for jack-detect |
| 22 | 2: Use JD1_2 pin for jack-detect |
| 23 | 3: Use JD2 pin for jack-detect |
| 24 | |
| 25 | - realtek,jack-detect-not-inverted |
| 26 | 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 not |
| 28 | inverted. |
| 29 | |
| 30 | - realtek,over-current-threshold-microamp |
| 31 | u32, micbias over-current detection threshold in µA, valid values are |
| 32 | 600, 1500 and 2000µA. |
| 33 | |
| 34 | - realtek,over-current-scale-factor |
| 35 | u32, micbias over-current detection scale-factor, valid values are: |
| 36 | 0: Scale current by 0.5 |
| 37 | 1: Scale current by 0.75 |
| 38 | 2: Scale current by 1.0 |
| 39 | 3: Scale current by 1.5 |
