Subject: [PATCH v2 2/4] gpio: remove GENERIC_GPIO config option
Date: Mon, 8 Apr 2013 11:32:28 -0700 [thread overview]
Message-ID: <1365445950-5736-3-git-send-email-gnurou@gmail.com> (raw)
In-Reply-To: <1365445950-5736-1-git-send-email-gnurou@gmail.com>
From: Alexandre Courbot <acourbot@nvidia.com>
GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code
and all driver code has been switch to depend on GPIOLIB. It is thus
safe to have GENERIC_GPIO removed.
Signed-off-by: Alexandre Courbot <acourbot@nvidia.com>
