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.

This is sufficient to allow boot of the Lager board with
a console without boards-lager.c compiled into the kernel.
This is an example of a minimal but still useful initialisation
of the board using DT as much as possible.
As such it is the same as the boot of Lager that can be achieved
without a board file. The intention of adding this file
is to facilitate further work to allow board specific devices to be
initialised via DT.

These changes from 30 individual branches for the most part update device
tree files, but there are also a few source code changes that have crept
in this time, usually in order to atomically move over a driver from
using hardcoded data to DT probing.
A number of platforms change their DT files to use the C preprocessor,
which is causing a bit of churn, but that is hopefully only this once.
There are a few conflicts with the other branches unfortunately:
* in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
from multiple branches. Need to be careful to have the right
set of closing braces as git gets this one wrong.
* In kirkwood.dtsi, one 'ranges' line got split into two lines, while
another line got added. Order of the lines does not matter.
* in sama5d3.dtsi, some cleanup was merged the wrong way, causing
a bogus conflict. We want the 'dmas' and 'dma-names' properties
to get added here.
* Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
* Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

Provide alternate board code for the kzm9g to demonstrate
how DT may be used given the current state of driver
device tree support. This is intended to act as a reference
for mach-shmobile developers.
Some notes:
* Brings up the GIC interrupt handler using device tree
* Brings up the following device using device tree:
- MMCIF (MMC)
* Does not bring up the INTC interrupt controller at all,
thus external devices may not be used. In particular,
the SMSC ethernet device may not be used and thus
NFS root may not be used.
* Uses existing C code and not device tree to initialise the following,
which are needed for a working board:
- SCIF (Serial)
- CMT (Clock)
- PFC (GPIO)
To use this alternate board code instead of the normal board code,
CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config.
And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used.
Includes fix by Thierry Reding to no longer use gic_handle_irq()

base address storage and for the early SCU setup
code in shmobile_secondary_vector_scu.
With this patch applied r8a7779, sh73a0 and EMEV2
all make use of the global shmobile_scu_base
variable. However only sh73a0 makes use of the SCU
bring up code in shmobile_secondary_vector_scu.

Rename headsmp-sh73a0.S into headsmp-scu.S and
introduce shmobile_secondary_vector_scu().
The goal is to be able to share the function
above between all mach-shmobile SoCs that use
SCU for SMP. So far only sh73a0 use this.
At this time the SCU base address is still hard
coded in headsmp-scu.S to 0xf0000000, but this
will be changed in the future.

This is a larger set of new functionality for the existing SoC families,
including:
* vt8500 gains support for new CPU cores, notably the Cortex-A9 based wm8850
* prima2 gains support for the "marco" SoC family, its SMP based cousin
* tegra gains support for the new Tegra4 (Tegra114) family
* socfpga now supports a newer version of the hardware including SMP
* i.mx31 and bcm2835 are now using DT probing for their clocks
* lots of updates for sh-mobile
* OMAP updates for clocks, power management and USB
* i.mx6q and tegra now support cpuidle
* kirkwood now supports PCIe hot plugging

When booting secondary CPUs we have used the main CPU to set up the
Snoop Control Unit flags of these CPUs. It is a cleaner approach
if every CPU takes care of its own flags. We avoid the need for
locking and the program logic is more concise. With this patch the file
headsmp-sh73a0.S is added that contains a startup vector for secondary CPUs
that sets up its own SCU flags.
Further in sh73a0_smp_prepare_cpus() we can rely on the generic ARM helper
scu_power_mode(). This is possible as we don't cross borders anymore (every
CPU handles its own flags) and need no locking. So we can throw out the
needless function modify_scu_cpu_psr().

The role of the only function in the common.c file in
arch/arm/mach-shmobile, shmobile_init_late(), is to call two
initializers whose definitions depend on kernel configuration
options. Those initializers may very well be called from a static
inline function in arm/mach-shmobile/include/mach/common.h,
though, in which makes the code a bit easier to read. Moreover,
the common.c may be dropped entirely then.

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.
