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,pow-ldo2-gpio =
|
<&gpio TEGRA_GPIO(V, 3) GPIO_ACTIVE_HIGH>;
|
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 */
|
};
