hwmon: (nct6775) Add support for NCT6792D
NCT6792D is similar to NCT6791D. Only beep control and temperature monitoring registers are different. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

If you say yes here you get support for the hardware monitoring

functionality of the Nuvoton NCT6106D, NCT6775F, NCT6776F, NCT6779D,
|

NCT6791D and compatible Super-I/O chips. This driver replaces the

w83627ehf driver for NCT6775F and NCT6776F.

NCT6791D, NCT6792D 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.
