-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>;
-};
