| RT5665/RT5666 audio CODEC |
| |
| This device supports I2C only. |
| |
| Required properties: |
| |
| - compatible : One of "realtek,rt5665", "realtek,rt5666". |
| |
| - reg : The I2C address of the device. |
| |
| - interrupts : The CODEC's interrupt output. |
| |
| Optional properties: |
| |
| - realtek,in1-differential |
| - realtek,in2-differential |
| - realtek,in3-differential |
| - realtek,in4-differential |
| Boolean. Indicate MIC1/2/3/4 input are differential, rather than single-ended. |
| |
| - realtek,dmic1-data-pin |
| 0: dmic1 is not used |
| 1: using GPIO4 pin as dmic1 data pin |
| 2: using IN2N pin as dmic2 data pin |
| |
| - realtek,dmic2-data-pin |
| 0: dmic2 is not used |
| 1: using GPIO5 pin as dmic2 data pin |
| 2: using IN2P pin as dmic2 data pin |
| |
| - realtek,jd-src |
| 0: No JD is used |
| 1: using JD1 as JD source |
| |
| - realtek,ldo1-en-gpios : The GPIO that controls the CODEC's LDO1_EN pin. |
