Subject: [PATCH 2/3] of: of_gpiochip_add is needed only for gpiolib
Date: Mon, 31 Jan 2011 23:25:50 +0800 [thread overview]
Message-ID: <1296487551-30938-2-git-send-email-thomas@wytron.com.tw> (raw)
In-Reply-To: <AANLkTimS70uHqmv3jhr+7mPz4QFKXRXuFnWj8s3EpKsO-JsoAwUIsXosN+BqQ9rBEUg@public.gmane.org>
Some gpio drivers may not use gpiolib. In this case, struct gpio_chip
is not defined and of_gpiochip_add/remove are not needed.
