^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Description

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) This driver implements support for the Analog Devices ADT7411 chip. There may
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) be other chips that implement this interface.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) SPI-compatible 4-wire interface. It provides a 10-bit analog to digital
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) converter which measures 1 temperature, vdd and 8 input voltages. It has an
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) internal temperature sensor, but an external one can also be connected (one
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) loses 2 inputs then). There are high- and low-limit registers for all inputs.
