Magnus Damm af164ca33d ARM: shmobile: Get rid of redundant EMEV2 mach callbacks
Update the EMEV2 specific SoC callbacks to get rid
of the calls to of_clk_init() and of_platform_populate().
Those calls are by default executed by the functions in
the shared ARM code in case the SoC specific mach
callbacks are NULL.

Linus Torvalds fa91515cbf ARM: Renesas SoC cleanup, refactoring and more SMP support
Lots of cleanup and refactoring and some SMP additions for Renesas
 platforms.  Due to some inter-dependencies with other arm-soc
 branches, this Renesas stuff was separated out for sending after the
 other branches were merged.
 
 Highlights:
 - remove unused board support and cleanup of unused headers
 - refactoring of init and device registration
 - simplify IRQ initialization
 
 Conflicts: Too many. Most of these are because Simon chose to send
 some board updates through the V4L tree that ends up colliding with
 the main platform changes. We'll work with him on sorting out his
 workflow:
 
 - arch/arm/boot/dts/r8a7740.dtsi:
   - Add/add conflict in a devicetree file (keep both)
 
 - arch/arm/mach-shmobile/Makefile:
   - Splitting out of clock files collides with intc move to DT.
     Keep HEAD version but remove intc-* files for R8A7740 and R8A7779.
 
 - arch/arm/mach-shmobile/board-bockw.c:
   - Keep HEAD but remove i2c, hspi and mmc device init calls
 
 - arch/arm/mach-shmobile/board-marzen.c
   - Remove mach/hardware.h include and r8a7779_add_usb_phy_device() call,
     everything else stays.
 
 - arch/arm/mach-shmobile/include/mach/r8a7778.h:
   - From HEAD, Keep camera-rcar.h include and r8a7778_add_vin_device()
   - From branch, keep everything
 
 - arch/arm/mach-shmobile/include/mach/r8a7779.h:
   - From HEAD, Keep only camera-rcar.h include and r8a7779_add_vin_device()
 
 - arch/arm/mach-shmobile/setup-r8a7778.c
   - Keep HEAD, but drop the MMC section (struct resource + add_mmc_device())
   - take the new function name from our side (r8a7778_add_dt_devices())
 
 - arch/arm/mach-shmobile/setup-r8a7779.c
   - Keep HEAD, but drop r8a7779_add_usb_phy_device()
 
 I've also pushed a test-merge2 branch where you can see how I resolved
 them.

Rob Herring 520f7bd733 irqchip: Move ARM gic.h to include/linux/irqchip/arm-gic.h
Now that we have GIC moved to drivers/irqchip and all GIC DT init for
platforms using irqchip_init, move gic.h and update the remaining
includes.

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.

Magnus Damm 3d5de27174 mach-shmobile: Emma Mobile EV2 DT support V3
This is EMEV2 DT support V3. The support is limited to
whatever devices that are complied in the kernel. At this
point we have UARTs handled by "em-uart" and a timer
handled by "em-sti". Clocks and SMP are not supported.

Magnus Damm 088efd9273 mach-shmobile: Emma Mobile EV2 GPIO support V3
Tie in the Emma Mobile GPIO driver "em-gio" to
support the GPIOs on Emma Mobile EV2.

A static IRQ range is used to allow boards to
hook up their platform devices to the GPIOs.

DT support is still on the TODO for the GPIO driver,
so only platform device support is included here.

Magnus Damm bd5a875d90 mach-shmobile: Emma Mobile EV2 SMP support V3
This is V3 of Emma Mobile EV2 SMP support.

At this point only the most basic form of SMP operation
is supported. TWD and CPU Hotplug support is excluded.

Tied to both the Emma Mobile EV2 and the KZM9D board
due to the need to switch on board in platsmp.c and
the newly introduced need for static mappings.

The static mappings are needed to allow hardware
acces early during boot when SMP is initialized.
This early requirement forces us to also map in
the SMU registers.
