WebFeb 10, 2014 · [email protected], Philipp Zabel . [PATCH] reset: Add generic GPIO reset driver. This driver allows GPIO lines to be used as reset signals. It has two main use cases: 1) Allow drivers to reset their hardware via a GPIO line in a standard fashion as supplied by the reset framework. Web* gpio_led_register_device - register a gpio-led device * @pdata: the platform data used for the new device * * Makes a copy of pdata and pdata->leds and registers a new leds-gpio device * with the result. This allows to have pdata and pdata-leds in .init.rodata * and so saves some bytes compared to a static struct platform_device with
