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()
