Kernel driver adt7411
=====================
Supported chips:
* Analog Devices ADT7411
Prefix: 'adt7411'
Addresses scanned: 0x48, 0x4a, 0x4b
Datasheet: Publicly available at the Analog Devices website
Author: Wolfram Sang (based on adt7470 by Darrick J. Wong)
Description
-----------
This driver implements support for the Analog Devices ADT7411 chip. There may
be other chips that implement this interface.
The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an
SPI-compatible 4-wire interface. It provides a 10-bit analog to digital
converter which measures 1 temperature, vdd and 8 input voltages. It has an
internal temperature sensor, but an external one can also be connected (one
loses 2 inputs then). There are high- and low-limit registers for all inputs.
Check the datasheet for details.

================ =================
in0_input vdd voltage input
in[1-8]_input analog 1-8 input
temp1_input temperature input
================ =================
Besides standard interfaces, this driver adds (0 = off, 1 = on):
============== =======================================================
adc_ref_vdd Use vdd as reference instead of 2.25 V
fast_sampling Sample at 22.5 kHz instead of 1.4 kHz, but drop filters
no_average Turn off averaging over 16 samples
============== =======================================================
Notes
-----
SPI, external temperature sensor and limit registers are not supported yet.
