If you say yes here you get support for the hardware monitoring
functionality of the Nuvoton NCT6106D, NCT6775F, NCT6776F, NCT6779D,
NCT6791D, NCT6792D and compatible Super-I/O chips. This driver
replaces the w83627ehf driver for NCT6775F and NCT6776F.
NCT6791D, NCT6792D, NCT6793D, and compatible Super-I/O chips. This
driver replaces the w83627ehf driver for NCT6775F and NCT6776F.
This driver can also be built as a module. If so, the module
will be called nct6775.
