+Description
+-----------
+
+This driver implements support for the Texas Instruments ADS1015/ADS1115.
+
+This device is a 12/16-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:
