    +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.
