| RT5677 audio CODEC |
| |
| This device supports I2C only. |
| |
| Required properties: |
| |
| - compatible : "realtek,rt5677". |
| |
| - reg : The I2C address of the device. |
| |
| - interrupts : The CODEC's interrupt output. |
| |
| - gpio-controller : Indicates this device is a GPIO controller. |
| |
| - #gpio-cells : Should be two. The first cell is the pin number and the |
| second cell is used to specify optional parameters (currently unused). |
| |
| Optional properties: |
| |
| - realtek,pow-ldo2-gpio : The GPIO that controls the CODEC's POW_LDO2 pin. |
| |
| - realtek,in1-differential |
| - realtek,in2-differential |
| - realtek,lout1-differential |
| - realtek,lout2-differential |
| - realtek,lout3-differential |
| Boolean. Indicate MIC1/2 input and LOUT1/2/3 outputs are differential, |
| rather than single-ended. |
| |
| Pins on the device (for linking into audio routes): |
| |
| * IN1P |
| * IN1N |
| * IN2P |
| * IN2N |
| * MICBIAS1 |
| * DMIC1 |

| Example: |
| |
| rt5677 { |
| compatible = "realtek,rt5677"; |
| reg = <0x2c>; |
| interrupt-parent = <&gpio>; |
| interrupts = <TEGRA_GPIO(W, 3) GPIO_ACTIVE_HIGH>; |
| |
| gpio-controller; |
| #gpio-cells = <2>; |
| |
| realtek,pow-ldo2-gpio = |
| <&gpio TEGRA_GPIO(V, 3) GPIO_ACTIVE_HIGH>; |
| realtek,in1-differential = "true"; |
| }; |
