WebThe code implementing a gpio_chip should support multiple instances of the controller, preferably using the driver model. That code will configure each gpio_chip and issue gpiochip_add(), gpiochip_add_data(), or devm_gpiochip_add_data().Removing a GPIO controller should be rare; use gpiochip_remove() when it is unavoidable. Often a … WebThese output configuration modes are either push-pull or open drain. This is shown below in the GPIO port output type register (GPIOx_OTYPER), which allows for the selection of either Output push-pull or Output open-drain. By default, all output GPIO pins are in push-pull state, unless open-drain state is explicitly selected with this register.
