Merge tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc-specific updates, take 2 from Olof Johansson: "This branch converts the MXS Freescale platform to use irqdomains and sparse IRQ, in preparation for DT probing and multiplatform kernels." * tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: mxs: remove mach/irqs.h ARM: mxs: select SPARSE_IRQ ARM: mxs: adopt irq_domain support for icoll driver ARM: mxs: select MULTI_IRQ_HANDLER ARM: mxs: retrieve timer irq from device tree gpio/mxs: adopt irq_domain support for mxs gpio driver
