The primary example is a platform with one pin controller and two identical GPIO controllers, one of the GPIO controllers is using a pin control backend. Since the GPIO driver has to call pinctrl_request_gpio() etc, it needs something to hold on to if there is no backing pin controller for one of them. Yours, Linus Walleij
