219 All the chips supported by this driver are LPC Super-I/O chips, accessed
220 through the LPC bus (ISA-like I/O ports). The IT8712F additionally has an

235 These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
238 rotation speed sensors, 8 voltage sensors, associated alarms, and chassis
247 is stored in the Super-I/O configuration space. Due to technical limitations,
258 IT8783E/F, and late IT8712F and IT8705F also have optional 16-bit tachometer
260 not compatible with the older chips and revisions. The 16-bit tachometer mode

275 to IT8728F. It only supports 16-bit fan mode. Both chips support up to 6 fans.
277 The IT8790E, IT8792E/IT8795E and IT87952E support up to 3 fans. 16-bit fan
280 The IT8732F supports a closed-loop mode for fan control, but this is not
287 triggered if the rotation speed has dropped below a programmable limit. When
288 16-bit tachometer counters aren't used, fan readings can be divided by
