adm1026hm -- Analog 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 config- ured 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 <>.
It's not possible to determine if either a sensor is not connected, or the monitored device is producing no output. Therefore, unconnected sen- sors will show outputs of 0. The adm1026hm driver does not support checking or altering limit values, interrupt output, nor the built-in EEPROM. NetBSD 9.2 December 11, 2015 NetBSD 9.2
