Merge tag 'davinci-for-v3.14/gpio' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into next/drivers

From Sekhar Nori:
DaVinci GPIO driver updates
---------------------------

This pull request contains updates to DaVinci GPIO driver and the
resultant platform code changes. The updates include DT-conversion and
changes to make the driver cross-platform ready.

* tag 'davinci-for-v3.14/gpio' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
  gpio: davinci: don't create irq_domain in case of unbanked irqs
  gpio: davinci: use chained_irq_enter/chained_irq_exit API
  gpio: davinci: add OF support
  gpio: davinci: remove unused variable intc_irq_num
  gpio: davinci: convert to use irqdomain support.
  gpio: introduce GPIO_DAVINCI kconfig option
  gpio: davinci: get rid of DAVINCI_N_GPIO
  gpio: davinci: use {readl|writel}_relaxed() instead of __raw_*
