Merge branch 'samsung/exynos-multiplatform-drivers' into late/multiplatform
This series contains the final pieces for Exynos multiplatform support:
Most of the patches are about the exynos-combiner irqchip, which is
converted to not rely on platform provided constants.
* samsung/exynos-multiplatform-drivers:
ARM: exynos: restore mach/regs-clock.h for exynos5
irqchip: exynos: look up irq using irq_find_mapping
irqchip: exynos: pass irq_base from platform
irqchip: exynos: localize irq lookup for ATAGS
irqchip: exynos: allocate combiner_data dynamically
irqchip: exynos: pass max combiner number to combiner_init
ARM: exynos: add missing properties for combiner IRQs
clocksource: exynos_mct: remove platform header dependency
clk: exynos: prepare for multiplatform
