| 2 | |
| 3 | This device supports I2C only. |
| 4 | |
| 5 | Required properties: |
| 6 | |
| 7 | - compatible : "realtek,rt5660". |
| 8 | |
| 9 | - reg : The I2C address of the device. |
| 10 | |
| 11 | Optional properties: |
| 12 | |
| 13 | - clocks: The phandle of the master clock to the CODEC |
| 14 | - clock-names: Should be "mclk" |
| 15 | |
| 16 | - realtek,in1-differential |
| 17 | - realtek,in3-differential |
| 18 | Boolean. Indicate MIC1/3 input are differential, rather than single-ended. |
| 19 | |
| 20 | - realtek,poweroff-in-suspend |
| 21 | Boolean. If the codec will be powered off in suspend, the resume should be |
| 22 | added delay time for waiting codec power ready. |
| 23 | |
| 24 | - realtek,dmic1-data-pin |
| 25 | 0: dmic1 is not used |
| 26 | 1: using GPIO2 pin as dmic1 data pin |
| 27 | 2: using IN1P pin as dmic1 data pin |
| 28 | |
