Merge tag 'davinci-for-v3.13/gpio' of git://git.kernel.org/pub/scm/li…

…nux/kernel/git/nsekhar/linux-davinci into next/drivers From Sekhar Nori, GPIO driver updates for DaVinci: This pull request moves DaVinci GPIO driver to use platform device framework and the corresponding changes needed to keep GPIO working on existing DaVinci boards. This is a pre-requisite to DT support for GPIO. * tag 'davinci-for-v3.13/gpio' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci: ARM: davinci: gpio: use gpiolib API instead of inline functions ARM: davinci: board: gpio device creation ARM: davinci: da8xx boards: gpio device creation ARM: davinci: support gpio platform device ARM: davinci: da8xx: support gpio platform device gpio: davinci: move to platform device gpio: davinci: coding style correction Signed-off-by: Olof Johansson <olof@lixom.net>
