| RT5650/RT5645 audio CODEC |
| |
| This device supports I2C only. |
| |
| Required properties: |
| |
| - compatible : One of "realtek,rt5645" or "realtek,rt5650". |
| |
| - reg : The I2C address of the device. |
| |
| - interrupts : The CODEC's interrupt output. |
| |
| Optional properties: |
| |
| - hp-detect-gpios: |
| a GPIO spec for the external headphone detect pin. If jd-mode = 0, |
| we will get the JD status by getting the value of hp-detect-gpios. |
| |
| - realtek,in2-differential |
| Boolean. Indicate MIC2 input are differential, rather than single-ended. |
| |
| - realtek,dmic1-data-pin |
| 0: dmic1 is not used |
| 1: using IN2P pin as dmic1 data pin |
| 2: using GPIO6 pin as dmic1 data pin |
| 3: using GPIO10 pin as dmic1 data pin |
| 4: using GPIO12 pin as dmic1 data pin |
| |
| - realtek,dmic2-data-pin |
| 0: dmic2 is not used |
| 1: using IN2N pin as dmic2 data pin |
| 2: using GPIO5 pin as dmic2 data pin |
| 3: using GPIO11 pin as dmic2 data pin |
| |
| -- realtek,jd-mode : The JD mode of rt5645/rt5650 |
| 0 : rt5645/rt5650 JD function is not used |
| 1 : Mode-0 (VDD=3.3V), two port jack detection |
| 2 : Mode-1 (VDD=3.3V), one port jack detection |
| 3 : Mode-2 (VDD=1.8V), one port jack detection |
