| 2 | |
| 3 | This device supports I2C only. |
| 4 | |
| 5 | Required properties: |
| 6 | |
| 7 | - compatible : "realtek,rt5640". |
| 8 | |
| 9 | - reg : The I2C address of the device. |
| 10 | |
| 11 | - interrupts : The CODEC's interrupt output. |
| 12 | |
| 13 | Optional properties: |
| 14 | |
| 15 | - realtek,in1-differential |
| 16 | - realtek,in2-differential |
| 17 | Boolean. Indicate MIC1/2 input are differential, rather than single-ended. |
| 18 | |
| 19 | - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. |
