+title: Analog Devices MAX98396 Speaker Amplifier Device Tree Bindings
+
+maintainers:
+  - Ryan Lee <ryans.lee@analog.com>
+
+description:
+  The MAX98396 is a mono Class-DG speaker amplifier with I/V sense.
+  The device provides a PCM interface for audio data and a standard
+  I2C interface for control data communication.
+  The MAX98397 is a variant of MAX98396 with wide input supply range.
+
+properties:
+  compatible:
+    enum:
+      - adi,max98396
+      - adi,max98397
+  reg:
+    maxItems: 1
+    description: I2C address of the device.

+    description: slot number of the voltage sense monitor
+    minimum: 0
+    maximum: 15
+    default: 0
+
+  adi,imon-slot-no:
+    description: slot number of the current sense monitor
+    minimum: 0
+    maximum: 15
+    default: 0
+
+  adi,spkfb-slot-no:
+    description: slot number of speaker DSP monitor
+    minimum: 0
+    maximum: 15
+    default: 0
+
+  adi,interleave-mode:
+    type: boolean
+    description: For cases where a single combined channel for the I/V sense data is not sufficient,
+                the device can also be configured to share a single data output channel on alternating frames.
+                In this configuration, the current and voltage data will be frame interleaved on a single output channel.
