OMAP GPIOs have many usages or use cases, so we can use gpiolib to simplify access to GPIOs. If GPIOs has only one usage or use case, it is not necessary to access GPIOs by gpiolib. Now this kind of DMA controllers are only used by MUSB or only for MUSB, so it doesn't matter to access them by dmaengine or not. thanks, -- Lei Ming -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
