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

  26 sysfs-Interface
  27 ---------------
  28
  29 in0_input       - vdd voltage input
  30 in[1-8]_input   - analog 1-8 input
  31 temp1_input     - temperature input
  32
  33 Besides 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
