This was tested on actual hardware and found to work fine, but currently
the official specifications of this chip could not be obtained to
confirm the numbers.

Say yes here to support GPIO functionality of IT87xx Super I/O chips.
This driver is tested with ITE IT8728 and IT8732 Super I/O chips, and
- supports the IT8761E, IT8620E and IT8628E Super I/O chip as well.
+ supports the IT8761E, IT8613, IT8620E, and IT8628E Super I/O chips as
+ well.
To compile this driver as a module, choose M here: the module will
be called gpio_it87
