No I just meant that the driver file in drivers/pinctrl/pinctrl-it87.c should
implement pinctrl, gpiolib (struct gpio_chip) and any GPIO
IRQs (struct irq_chip) in that one and the same file.

The MFD device will spawn cells/children as usual for HWMON and
other stuff, but the cell named "pinctrl-it87" (or however you
name it) should take care of all the pinctrl and GPIO stuff.
