Devices ADM1026 complete thermal system management controller
adm1026hm* at iic0 addr 0x2e: ADM1026 hardware
monitor: rev. 0x4, step. 0x5
adm1026hm*: 8 fans, 3 temperatures, 15 voltages
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.

The adm1026hm
driver was written by
Julian Coleman
<jcoleman@NetBSD.org>.
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.
