These functions have been introduced by commit 10a8c383 (irq: introduce entry and exit functions for chained handlers) in asm/mach/irq.h. This patch moves them to linux/irqchip/chained_irq.h so that generic irqchip drivers do not rely on architecture specific header files.

Exynos boot is broken with commit 0529e315 (ARM: use common irqchip_init for GIC init). This commit split the irqchip initialization into 2 calls to of_irq_init. This does not work because of_irq_init requires interrupt parents to be in the match list. Rather than reverting exynos changes, make it do the proper thing by using IRQCHIP_DECLARE. This requires moving the combiner code to drivers/irqchip.

The recent commit "ARM: EXYNOS: add support for EXYNOS5440 SoC" broke support for exynos5250 because of_machine_is_compatible() was used too early in the boot process. It also probably meant that the exynos5440 failed to use the proper iotable. Switch to use of_flat_dt_is_compatible() in both of these cases. The failure I was seeing in exynos5250 because of this was: Division by zero in kernel.

Commit a5238e36 (spi: s3c64xx: move controller information into driver data) introduced separate device names for the different subtypes of the spi controller but forgot to set these in the relevant machines. To fix this introduce a s3c64xx_spi_setname function and populate all Samsung arches with the correct names. The function resides in a new header, as the s3c64xx-spi.h contains driver platform data and should therefore at some later point move out of the Samsung include dir. Tested on a s3c2416-based machine.

A seperate bus_type instance is not required for EXYNOS5. The existing bus_type instance used with EXYNOS4 is sufficient for both EXYNOS4 and EXYNOS5. This also solves issue of uninitialized usage of exynos4_subsys in EXYNOS4 power management code that is reused for EXYNOS5 also. In addition to that, the existing exynos4_subsys bus_type is renamed to exynos_subsys to indicate that it is reused on both EXYNOS4 and EXYNOS5 platforms.
