| 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,reset-gpio : The GPIO that controls the CODEC's RESET pin. Active low. | |
| - 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. | |
| - realtek,gpio-config | |
| Array of six 8bit elements that configures GPIO. | |
| 0 - floating (reset value) | |
| 1 - pull down | |
| 2 - pull up | |
| - realtek,jd1-gpio | |
| Configures GPIO Mic Jack detection 1. | |
| Select 0 ~ 3 as OFF, GPIO1, GPIO2 and GPIO3 respectively. | |
| - realtek,jd2-gpio | |
| - realtek,jd3-gpio | |
| Configures GPIO Mic Jack detection 2 and 3. | |
| Select 0 ~ 3 as OFF, GPIO4, GPIO5 and GPIO6 respectively. | |

| realtek,reset-gpio = <&gpio TEGRA_GPIO(BB, 3) GPIO_ACTIVE_LOW>; | |
| realtek,in1-differential = "true"; | |
| realtek,gpio-config = /bits/ 8 <0 0 0 0 0 2>; /* pull up GPIO6 */ | |
| realtek,jd2-gpio = <3>; /* Enables Jack detection for GPIO6 */ | |
