Merge tag 'irq' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull arm-soc sparse IRQ conversion from Arnd Bergmann: "The I.MX platform is getting converted to use sparse IRQs. We are doing this for all platforms over time, because this is one of the requirements for building a multiplatform kernel, and generally a good idea." * tag 'irq' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: imx: select USE_OF ARM: imx: Fix build error due to missing irqs.h include ARM: imx: enable SPARSE_IRQ for imx platform ARM: fiq: change FIQ_START to a variable tty: serial: imx: remove the use of MXC_INTERNAL_IRQS ARM: imx: remove unneeded mach/irq.h inclusion i2c: imx: remove unneeded mach/irqs.h inclusion ARM: imx: add a legacy irqdomain for mx31ads ARM: imx: add a legacy irqdomain for 3ds_debugboard ARM: imx: pass gpio than irq number into mxc_expio_init ARM: imx: leave irq_base of wm8350_platform_data uninitialized dma: ipu: remove the use of ipu_platform_data ARM: imx: move irq_domain_add_legacy call into avic driver ARM: imx: move irq_domain_add_legacy call into tzic driver gpio/mxc: move irq_domain_add_legacy call into gpio driver ARM: imx: eliminate macro IRQ_GPIOx() ARM: imx: eliminate macro IOMUX_TO_IRQ() ARM: imx: eliminate macro IMX_GPIO_TO_IRQ()
