Merge branch 'imx/sparse-irq' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/irq
From Shawn Guo <shawn.guo@linaro.org>, this makes it possible to use
sparse irqs with mach-imx.
* 'imx/sparse-irq' of git://git.linaro.org/people/shawnguo/linux-2.6:
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()
