Subject: [PATCH] arm64: select ARCH_WANT_OPTIONAL_GPIOLIB
Date: Thu, 21 Feb 2013 11:44:51 +0100 [thread overview]
Message-ID: <2173132.bncoOm6QsM@wuerfel> (raw)
In-Reply-To: <CACxGe6tVk4na2yLi-6r1fTv5QqzgePbo6K+ZtEt-VOy25DQxVQ@mail.gmail.com>
An architecture should not unconditionally enable 'GENERIC_GPIO'
without providing an implementation. In case of arm64, selecting
ARCH_WANT_OPTIONAL_GPIOLIB is the right solution, because it
lets us enable GPIOLIB when configuring the kernel, and that
implicitly turns on GENERIC_GPIO.

It was wrong, the new version below is good though. Tested with defconfig
and allyesconfig on arm64. I found a few more trivial issues with arm64
allyesconfig that I fixed up as well. I'll send separate patches
for those.
