Olof Johansson f8060f5446 Initial irqchip init infrastructure and GIC and VIC clean-ups
This creates irqchip initialization infrastructure from Thomas
 Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips
 and adapted to use the new infrastructure. All DT enabled platforms
 using GIC and VIC are converted over to use the new irqchip_init.

Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

Padmavathi Venna a08485d8fd ASoC: Samsung: Do not register samsung audio dma device as pdev
Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a
platform_device. This didn't represent the hardware well, since there
was no separate hardware associated with this platform_device; it was a
virtual device with sole purpose to call snd_soc_register_platform().

This change removes the platform_device completely. Each Samsung DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.

Linus Torvalds f465d145d7 arm-soc: sweeping late_initcall cleanup
This is a patch series from Shawn Guo that moves from individual
 late_initcalls() to using a member in the machine structure to invoke
 a platform's late initcalls.
 
 This cleanup is a step in the move towards multiplatform kernels since
 it would reduce the need to check for compatible platforms in each and
 every initcall.

KyongHo Cho bca10b906f ARM: EXYNOS: Change System MMU platform device definitions
Handling System MMUs with an identifier is not flexible to manage
System MMU platform devices because of the following reasons:
1. A device driver which needs to handle System MMU must know the ID.
2. A System MMU may not present in some implementations of Exynos family.
3. Handling System MMU with IOMMU API does not require an ID.

This patch is the result of removing ID of System MMUs.
Instead, a device driver that needs to handle its System MMU must
use IOMMU API while its descriptor of platform device is given.

This patch also includes the following enhancements:
- A System MMU device becomes a child if its power domain device.
- clkdev

Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.
