Subject: [PATCH v2] gpio: Fix OF build problem on UM
Date: Fri, 19 Aug 2016 14:52:36 +0200 [thread overview]
Message-ID: <1471611156-4220-1-git-send-email-linus.walleij@linaro.org> (raw)
The UserMode (UM) Linux build was failing in gpiolib-of as it requires
ioremap()/iounmap() to exist, which is absent from UM. The non-existence
of IO memory is negatively defined as CONFIG_NO_IOMEM which means we
need to depend on HAS_IOMEM.
