+RT1011 Mono Class D Audio Amplifier
+
+This device supports I2C only.
+
+Required properties:
+
+- compatible : "realtek,rt1011".
+
+- reg : The I2C address of the device. This I2C address decide by
+        two input pins (ASEL1 and ASEL2).
+        -------------------------------------
+        |   ASEL2   |  ASEL1   |  Address   |
+        -------------------------------------
+        |     0     |    0     |   0x38     |
+        -------------------------------------
+        |     0     |    1     |   0x39     |
+        -------------------------------------
+        |     1     |    0     |   0x3a     |
+        -------------------------------------
+        |     1     |    1     |   0x3b     |
