help
This option enables support for GPIOs found on Fintek Super-I/O
chips F71869, F71869A, F71882FG, F71889F and F81866.
As well as Nuvoton Super-I/O chip NCT6116D.
As well as Nuvoton Super-I/O chip NCT6126D.
To compile this driver as a module, choose M here: the module will
be called f7188x-gpio.
