1ADS1015 (I2C)
2
3This device is a 12-bit A-D converter with 4 inputs.
4
5The inputs can be used single ended or in certain differential combinations.
6
7For configuration all possible combinations are mapped to 8 channels:
8 0: Voltage over AIN0 and AIN1.
9 1: Voltage over AIN0 and AIN3.
10 2: Voltage over AIN1 and AIN3.
11 3: Voltage over AIN2 and AIN3.
12 4: Voltage over AIN0 and GND.
13 5: Voltage over AIN1 and GND.
14 6: Voltage over AIN2 and GND.
15 7: Voltage over AIN3 and GND.
16
17Each channel can be configured individually:
18 - pga is the programmable gain amplifier (values are full scale)
19 0: +/- 6.144 V
20 1: +/- 4.096 V
21 2: +/- 2.048 V (default)
22 3: +/- 1.024 V
23 4: +/- 0.512 V
24 5: +/- 0.256 V
25 - data_rate in samples per second
26 0: 128
27 1: 250
28 2: 490
29 3: 920
30 4: 1600 (default)

32 6: 3300

39 - reg : I2C bus address of the device
40 - #address-cells : must be <1>
41 - #size-cells : must be <0>
42
43 The node contains child nodes for each channel that the platform uses.

13Description
14-----------
15
16This driver implements support for the Texas Instruments ADS1015.
17
18This device is a 12-bit A-D converter with 4 inputs.
19
20The inputs can be used single ended or in certain differential combinations.
21
22The inputs can be made available by 8 sysfs input files in0_input - in7_input:
23in0: Voltage over AIN0 and AIN1.
24in1: Voltage over AIN0 and AIN3.
25in2: Voltage over AIN1 and AIN3.
26in3: Voltage over AIN2 and AIN3.
27in4: Voltage over AIN0 and GND.
28in5: Voltage over AIN1 and GND.
29in6: Voltage over AIN2 and GND.
30in7: Voltage over AIN3 and GND.
31
32Which inputs are available can be configured using platform data or devicetree.
33
34By default all inputs are exported.
35
36Platform Data
37-------------
38
39In linux/i2c/ads1015.h platform data is defined, channel_data contains
40configuration data for the used input combinations:
41- pga is the programmable gain amplifier (values are full scale)
42 0: +/- 6.144 V
43 1: +/- 4.096 V
44 2: +/- 2.048 V
45 3: +/- 1.024 V
46 4: +/- 0.512 V
47 5: +/- 0.256 V
48- data_rate in samples per second
49 0: 128
50 1: 250
51 2: 490
52 3: 920
53 4: 1600
54 5: 2400
55 6: 3300
56
57Example:
58struct ads1015_platform_data data = {
59 .channel_data = {
60 [2] = { .enabled = true, .pga = 1, .data_rate = 0 },
61 [4] = { .enabled = true, .pga = 4, .data_rate = 5 },
62 }
63};
64
65In this case only in2_input (FS +/- 4.096 V, 128 SPS) and in4_input
66(FS +/- 0.512 V, 2400 SPS) would be created.
67

16SMSC SCH5627 Super I/O chips include complete hardware monitoring
17capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures.
18
19The hardware monitoring part of the SMSC SCH5627 is accessed by talking
20through an embedded microcontroller. An application note describing the
21protocol for communicating with the microcontroller is available upon
22request. Please mail me if you want a copy.

1307 This driver provides support for the LIS3* accelerometers, such as the
1308 LIS3LV02DL or the LIS331DL. In particular, it can be found in a number
1309 of HP laptops, which have the "Mobile Data Protection System 3D" or
1310 "3D DriveGuard" feature. On such systems the driver should load
1311 automatically (via ACPI alias). The accelerometer might also be found
1312 in other systems, connected via SPI or I2C. The accelerometer data is
1313 readable via /sys/devices/platform/lis3lv02d.

1315 This driver also provides an absolute input class device, allowing
1316 a laptop to act as a pinball machine-esque joystick. It provides also

1318 if the led infrastructure is activated, support for a led indicating
1319 disk protection will be provided as hp::hddprotect. For more
1320 information on the feature, refer to Documentation/hwmon/lis3lv02d.
