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 gpio_chip … Web* gpio_led_register_device - register a gpio-led device * @pdata: the platform data used for the new device * @id: platform ID * * Makes a copy of pdata and pdata->leds and registers a new leds-gpio device * with the result.
