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

233 IT8792E/IT8795E, IT87952E and SiS950 chips.
235 These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
244 though, so the functionality may not be available on a given system.
247 is stored in the Super-I/O configuration space. Due to technical limitations,
251 can't have both on a given board.
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
261 is enabled by the driver when one of the above chips is detected.
271 IT8728F. It only supports 3 fans, 16-bit fan mode, and the full speed 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
