NAME
adm1026hm —
Analog Devices ADM1026
complete thermal system management controller
SYNOPSIS
adm1026hm* at iic0 addr 0x2e: ADM1026 hardware monitor: rev. 0x4,
step. 0x5
adm1026hm*: 8 fans, 3 temperatures, 15 voltages
DESCRIPTION
The
adm1026hm driver provides support for the Analog Devices
ADM1026 hardware monitor. The chip possesses 8 fan speed sensors, 3
temperature sensors, and 17 voltage sensors. The number of each sensor type
configured by the driver depends on the chip configuration.
The values of the sensors are made available through the
envstat(8) interface.

BUGS
It's not possible to determine if either a sensor is not connected, or the
monitored device is producing no output. Therefore, unconnected sensors will
show outputs of 0.
The
adm1026hm driver does not support checking or altering
limit values, interrupt output, nor the built-in EEPROM.
