A pinctrl handle is used to setup a pull-up on the stusb1600 IRQ pin (that is open drain). When in ANALOG state, no pull-up can be applied in the GPIO HW controller, still the setting is done into the register. The pull-up is effective currently, only when the GPIO IRQ is requested. The correct setting is to use directly the GPIO, instead of ANALOG state.
