+ADS1015 (I2C)
+
+This device is a 12-bit A-D converter with 4 inputs.
+
+The inputs can be used single ended or in certain differential combinations.
+
+For configuration all possible combinations are mapped to 8 channels:
+0: Voltage over AIN0 and AIN1.
+1: Voltage over AIN0 and AIN3.
+2: Voltage over AIN1 and AIN3.
+3: Voltage over AIN2 and AIN3.
+4: Voltage over AIN0 and GND.
+5: Voltage over AIN1 and GND.
+6: Voltage over AIN2 and GND.
+7: Voltage over AIN3 and GND.
+
+Optional properties:
+
+ - exported-channels : exported_channels is a bitmask that specifies which
+ channels should be accessable by the user.
+
+Example:
+ads1015@49 {
+ compatible = "ti,ads1015";
+ reg = <0x49>;
+ exported-channels = <0x14>;
+};
+
+In this example only channel 2 and 4 would be accessable by the user.
