| RT5640/RT5639 audio CODEC |
| |
| This device supports I2C only. |
| |
| Required properties: |
| |
| - compatible : One of "realtek,rt5640" or "realtek,rt5639". |
| |
| - reg : The I2C address of the device. |
| |
| - interrupts : The CODEC's interrupt output. |
| |
| Optional properties: |
| |
| - realtek,in1-differential |
| - realtek,in2-differential |
| Boolean. Indicate MIC1/2 input are differential, rather than single-ended. |
| |
| - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. |
