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