Merge tag 'kill-plat-sparse-irq' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl into next/multiplatform

From Linus Walleij:

This patchset will:
- Move all remaining headers out of arch/arm/plat-nomadik/include/plat
  out to e.g. include/linux/platform_data
- Delete arch/arm/plat-nomadik
- Convert Nomadik and Ux500 to SPARSE_IRQ

* tag 'kill-plat-sparse-irq' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
  ARM: plat-nomadik: convert platforms to SPARSE_IRQ
  mfd/db8500-prcmu: use the irq_domain_add_simple()
  mfd/ab8500-core: use irq_domain_add_simple()
  ARM: plat-nomadik: move MTU, kill plat-nomadik
  ARM: plat-nomadik: move DMA40 header to <linux/platform_data>
  ARM: plat-nomadik: use DIV_ROUND_CLOSEST()
  ARM: plat-nomadik: pass IRQ to timer driver
  clk/ux500: explicitly include register header
  pinctrl/nomadik: merge old pincfg header
  pinctrl/nomadik: move the platform data header
  ARM: plat-nomadik: move NMK_GPIO_PER_CHIP into gpio-nomadik.h
  ARM: plat-nomadik: Introduce new DB8540 GPIO registers
