| 2 | |
| 3 | This device supports I2C only. |
| 4 | |
| 5 | Required 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 | |
| 13 | Optional 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 |
