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