-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.
-
-Pins on the device (for linking into audio routes):
-
- * IN1P
- * IN1N
- * IN2P
- * IN2N
- * MICBIAS1
- * DMIC1
- * DMIC2
- * DMIC3
- * DMIC4
- * LOUT1
- * LOUT2
- * LOUT3
-
-Example:
-
-rt5677 {
- compatible = "realtek,rt5677";
- reg = <0x2c>;
- interrupt-parent = <&gpio>;
- interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_HIGH>;
-
- gpio-controller;
- #gpio-cells = <2>;
-
- 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 */
-};
