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
