+
+description:
+  The MCTP I2C binding defines an MCTP endpoint on the I2C bus to
+  communicate with I2C peripherals using MCTP (DMTF specification DSP0237).
+
+  An mctp-i2c device must be attached to a hardware bus adapter which supports
+  slave functionality. The reg address must include I2C_OWN_SLAVE_ADDRESS.
+
+
+properties:
+  compatible:
+    const: mctp-i2c
+
+  reg:
+    maxItems: 1
+
+additionalProperties: true
+
+required:
+  - compatible
+  - reg
+
+examples:
+  - |
+    #include <dt-bindings/i2c/i2c.h>
+    i2c {
+        #address-cells = <1>;
+        #size-cells = <0>;
+
+        mctp@50 {
+            compatible = "mctp-i2c";
+            reg = <(0x50 | I2C_OWN_SLAVE_ADDRESS)>;
+        };
