This binding was moved over from hwmon some time ago so is a bit
unusual in terms of IIO bindings.  However, conversion was fairly
straight forwards.

I've listed both Dirk (who think wrote original binding) and Daniel
who added the IIO driver for this device.

Dropped Dirk as maintainer on this one as I don't have an up to date
address.  That leaves Daniel as the sole listed maintainer.

Hope that's fine!

Applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to maybe run some tests on it.

Thanks,

Jonathan

-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.
-
-Each channel can be configured individually:
- - pga is the programmable gain amplifier (values are full scale)
-    0: +/- 6.144 V
-    1: +/- 4.096 V
-    2: +/- 2.048 V (default)
-    3: +/- 1.024 V
-    4: +/- 0.512 V
-    5: +/- 0.256 V
- - data_rate in samples per second
-    0: 128
-    1: 250
-    2: 490
-    3: 920
-    4: 1600 (default)
-    5: 2400
-    6: 3300
-
-1) The /ads1015 node
-
-  Required properties:
-
-   - compatible : must be "ti,ads1015"
-   - reg : I2C bus address of the device
-   - #address-cells : must be <1>
-   - #size-cells : must be <0>
-
-  The node contains child nodes for each channel that the platform uses.
-
-  Example ADS1015 node:
-
-    ads1015@49 {
-	    compatible = "ti,ads1015";
-	    reg = <0x49>;
-	    #address-cells = <1>;
-	    #size-cells = <0>;
-
-	    [ child node definitions... ]
-    }
-
-2) channel nodes
-
-  Required properties:
-
-   - reg : the channel number
-
-  Optional properties:
-
-   - ti,gain : the programmable gain amplifier setting
-   - ti,datarate : the converter data rate
-
-  Example ADS1015 channel node:
-
-    channel@4 {
-	    reg = <4>;
-	    ti,gain = <3>;
-	    ti,datarate = <5>;
-    };
