From: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

This binding mainly serves to document the list of input and output pins
that may be used in a sound card's audio routing table.

This series doesn't depend on anything; it could be applied anywhere in
the ASoC tree.

+MAX98090 audio CODEC
+
+This device supports I2C only.
+
+Required properties:
+
+- compatible : "maxim,max98090".
+
+- reg : The I2C address of the device.
+
+- interrupts : The CODEC's interrupt output.
+
+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) GPIO_ACTIVE_HIGH>;
+};
