+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>;

+Kernel driver ads1015
+=====================
+
+Supported chips:
+  * Texas Instruments ADS1015
+    Prefix: 'ads1015'
+    Datasheet: Publicly available at the Texas Instruments website :
+               http://focus.ti.com/lit/ds/symlink/ads1015.pdf
+
+Authors:
+        Dirk Eibach, Guntermann & Drunck GmbH <eibach@gdsys.de>
+
+Description
+-----------
+
+This driver implements support for the Texas Instruments ADS1015.
+
+This device is a 12-bit A-D converter with 4 inputs.
+
+The inputs can be used single ended or in certain differential combinations.
+
+The inputs can be made available by 8 sysfs input files in0_input - in7_input:
+in0: Voltage over AIN0 and AIN1.
+in1: Voltage over AIN0 and AIN3.
+in2: Voltage over AIN1 and AIN3.
+in3: Voltage over AIN2 and AIN3.
+in4: Voltage over AIN0 and GND.
+in5: Voltage over AIN1 and GND.
+in6: Voltage over AIN2 and GND.
+in7: Voltage over AIN3 and GND.
+
+Which inputs are available can be configured using platform data or devicetree.
+
+By default all inputs are exported.
+
+Platform Data
+-------------
+
+In linux/i2c/ads1015.h platform data is defined, channel_data contains
+configuration data for the used input combinations:
+- pga is the programmable gain amplifier (values are full scale)
+  0: +/- 6.144 V
+  1: +/- 4.096 V
+  2: +/- 2.048 V
+  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
+  5: 2400
+  6: 3300
+
+Example:
+struct ads1015_platform_data data = {
+	.channel_data = {
+		[2] = { .enabled = true, .pga = 1, .data_rate = 0 },
+		[4] = { .enabled = true, .pga = 4, .data_rate = 5 },
+	}
+};
+
+In this case only in2_input (FS +/- 4.096 V, 128 SPS) and in4_input
+(FS +/- 0.512 V, 2400 SPS) would be created.
+
+Devicetree
+----------
+
+Configuration is also possible via devicetree:

-	  This driver provides support for the LIS3* accelerometers, such as the
-	  LIS3LV02DL or the LIS331DL. In particular, it can be found in a number
-	  of HP laptops, which have the "Mobile Data Protection System 3D" or
-	  "3D DriveGuard" feature. On such systems the driver should load
-	  automatically (via ACPI alias). The accelerometer might also be found
-	  in other systems, connected via SPI or I2C. The accelerometer data is
-	  readable via /sys/devices/platform/lis3lv02d.
-
-	  This driver also provides an absolute input class device, allowing
-	  a laptop to act as a pinball machine-esque joystick. It provides also
-	  a misc device which can be used to detect free-fall. On HP laptops,
-	  if the led infrastructure is activated, support for a led indicating
-	  disk protection will be provided as hp::hddprotect. For more
-	  information on the feature, refer to Documentation/hwmon/lis3lv02d.
-
-	  This driver can also be built as modules.  If so, the core module
-	  will be called lis3lv02d and a specific module for HP laptops will be
-	  called hp_accel.
-
-	  Say Y here if you have an applicable laptop and want to experience
-	  the awesome power of lis3lv02d.
