In particular, Configure the i2c controllers using a flattened device tree.

SCI serial controller and CMT clock source, whose drivers do not yet
support configuration using a flattened device tree, are still configured
using C code in order to allow booting of a board with this SoC.

*** Please note that the clock initialisation scheme used in
    this patch does not currently work with SMP as there
    is a yet to be resolved lock-up in workqueue initialisation.

    CONFIG_SMP must be disabled when using this code. ***

a3f22db510 ARM: mach-shmobile: sh73a0: Allow initialisation of GIC by DT
This allows the GIC interrupt controller of the sh73a0 SoC to be
initialised using a flattened device tree blob.

It does not allow the INTC interrupt controller which is also present on
the sh73a0 SoC to be enabled via device tree.  Nor does it handle sharing
of interrupts between the GIC and INTC interrupt controllers.

This limits the usefulness of this code to applications which only wish to
access devices which use interrupts that can be handled by the GIC
interrupt controller. Other applications should, for now, continue using
non-device tree initialisation of the sh72a0 interrupt controllers.

33419a69a5 ARM: SH-Mobile: sh73a0: Secondary CPUs handle own SCU flags
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().

6333ae1432 ARM: mach-shmobile: sh73a0 external IRQ wake update
Use sh73a0_set_wake() for external IRQ signals on sh73a0.

The sh73a0 IRQ hardware for external IRQ pins consists of
the INTCA interrupt controller and the GIC together doing
their best to limp along. These external IRQ pins are
treated as a special case where interrupts need to be
managed in both interrupt controllers in parallel.

The ->irq_set_wake() callback for the external IRQ pins
can be dealt with in the same way as INTCA-only without
involving the GIC. So this patch updates the external
IRQ pin code for sh73a0 to no longer involve the GIC.

Introduce an IP reset API for use on DaVinci SoC.

There is no existing "reset" framework support for SoC devices.

To support this, a new DaVinci specific API is added.

This private API will disappear with DT migration.  Some discussion
regarding a proposed DT "reset" binding is here:
https://patchwork.kernel.org/patch/1635051/

this patch adds tick timer, smp entries and generic DT machine
for SiRFmarco dual-core SMP chips.

with the added marco, we change the defconfig, using the same
defconfig, we get a zImage which can work on both prima2 and
marco.

f2a94192d9 ARM: PRIMA2: irq: make prima2 irq can work even we enable GIC for Marco
in Marco, we will use GIC. this patch prepares the handle_irq for prima2
to avoid the compiling errors since we want only one defconfig and zImage
for both prima2 and marco that means we will need handle_irq for both.

The clockevent core is able to figure out the best mult and shift,
calculate min_delta_ns and max_delta_ns, with the necessary info passed
into clockevents_config_and_register().  Use this combined configure
and register function where possible to make the codes less error prone
and gain some positive diff stat.
