The IT8728F, IT8771E, and IT8772E are considered compatible with the IT8721F,

until a datasheet becomes available (hopefully.)

The IT8603E is a custom design, hardware monitoring part is similar to
|

IT8728F. It only supports 16-bit fan mode, the full speed mode of the
|

fan is not supported (value 0 of pwmX_enable).

internal and scaled inside the chip (in7 (optional for IT8782F and IT8783E/F),
