12Description
13-----------
14
15This driver implements support for the Analog Devices ADT7411 chip. There may
16be other chips that implement this interface.
17
18The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an
19SPI-compatible 4-wire interface. It provides a 10-bit analog to digital
20converter which measures 1 temperature, vdd and 8 input voltages. It has an
21internal temperature sensor, but an external one can also be connected (one
22loses 2 inputs then). There are high- and low-limit registers for all inputs.

26sysfs-Interface
27---------------
28
29in0_input	- vdd voltage input
30in[1-8]_input	- analog 1-8 input
31temp1_input	- temperature input
32
33Besides standard interfaces, this driver adds (0 = off, 1 = on):
34
35  adc_ref_vdd	- Use vdd as reference instead of 2.25 V
36  fast_sampling	- Sample at 22.5 kHz instead of 1.4 kHz, but drop filters
37  no_average	- Turn off averaging over 16 samples

41
42SPI, external temperature sensor and limit registers are not supported yet.
