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.

can remove it for all machines and make it static. Move vic_handle_irq

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.

Nicolas Pitre 6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

Maurus Cuelenaere daf695fca8 arm: samsung: remove pixclock from several boards
Since "s3c-fb: Automatically calculate pixel clock when none is given",
there's no need for manually calculating the pixel clock anymore so remove
these lines and add the correct refresh rate where appropriately.

Ben Dooks f7be9abaa5 ARM: S3C64XX: Move core support to mach-s3c64xx
Move the core S3C64XX support to mach-s3c64xx as it is unlikely to be used
outside of this directory. Also move the SoC header files in with it.

This includes the clock, cpu, cpufreq, dma, gpiolib and pll support.

Ben Dooks 431107ea5b ARM: S3C64XX: Merge mach-s3c6400 and mach-s3c6410
As per discussions with Russell King on linux-arm-kernel, it appears that
both mach-s3c6400 and mach-s3c6410 are so close together that they should
simply be merged into mach-s3c64xx.

Note, this patch does not eliminate any of the bits that are still common,
it is simply a move of the two directories together, any further common
code will be eliminated or moved in further patches.
