-MAX98090 audio CODEC
-
-This device supports I2C only.
-
-Required properties:
-
-- compatible : "maxim,max98090" or "maxim,max98091".
-
-- reg : The I2C address of the device.
-
-- interrupts : The CODEC's interrupt output.
-
-Optional properties:
-
-- clocks: The phandle of the master clock to the CODEC
-
-- clock-names: Should be "mclk"
-
-- #sound-dai-cells : should be 0.
-
-- maxim,dmic-freq: Frequency at which to clock DMIC
-
-- maxim,micbias: Micbias voltage applies to the analog mic, valid voltages value are:
- 0 - 2.2v
- 1 - 2.55v
- 2 - 2.4v
- 3 - 2.8v
-
-Pins on the device (for linking into audio routes):
-
- * MIC1
- * MIC2
- * DMICL
- * DMICR
- * IN1
- * IN2
- * IN3
- * IN4
- * IN5
- * IN6
- * IN12
- * IN34
- * IN56
- * HPL
- * HPR
- * SPKL
- * SPKR
- * RCVL
- * RCVR
- * MICBIAS
-
-Example:
-
-audio-codec@10 {
- compatible = "maxim,max98090";
- reg = <0x10>;
- interrupt-parent = <&gpio>;
- interrupts = <TEGRA_GPIO(H, 4) IRQ_TYPE_LEVEL_HIGH>;
-};
