Currently, overo-related include files are organized as follow:

omap3-overo-tobi.dts omap3-overo-storm-tobi.dts
This is unpractical when one has to deal with SoC-specific pinmux
belonging to the omap3_pmx_core2 (defined in omap34xx/omap36xx),
for pins related to the processor board. With the current
hierarchy, such pinmux has to be defined in the expansion board's
.dts, which is not logical.
This patches reorganizes the files to add (yet another) abstraction
layer between the processor and the expansion boards.

The OMAP iommu driver performs the reset management for the
iommu instances in processor sub-systems using the omap_device
API which are currently supplied as platform data ops. Use pdata
quirks to maintain the functionality as the OMAP iommu driver
gets converted to use DT nodes, until the reset portions are
decoupled from omap_hwmod/omap_device into a separate reset
driver.
This patch adds the pdata quirks for the reset management of
iommus within the DSP (OMAP3 & OMAP4) and IPU subsystems (OMAP4).

The IOMMU DT adaptation support uses the device name instead
of an iommu object name. Fixup the ISP device archdata MMU
name at runtime if using DT-boot. This allows the OMAP3 camera
to be functional in both legacy and DT boots. The iommu object
names should eventually vanish when all the IOMMU users have
been converted to DT nodes.

The IVA MMU is not functional when used through the hwmod and
omap_device layers. Add fixes to clockdomain and hwmod data
to have it functional. The hwmod changes are needed to enable
the clock, and the SWSUP change is needed to wakeup the domain
because the power domain is programmed to be in RET, and there
is no automatic power domain switching to ON.

CONFIG_OMAP_IOMMU_IVA2 was defined originally to avoid conflicting
usage by tidspbridge and other iommu users. The same can be achieved
by marking the DT node disabled, so remove this obsolete flag and
the corresponding hwmod data can be enabled.

This patch prepare the transition to common clk for sam9 dt boards by
replacing the timer init callback.
Clocks registration cannot be done in early init callback (as formerly done
by the old clk implementation) because it requires dynamic allocation
which is not ready yet during early init.
In the other hand, at91 clocks must be registered before
at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver
request the master clk (mck).
A new function (at91sam9_dt_timer_init) is created to fullfil these needs.
This function registers all at91 clks using the dt definition before
calling the PIT init function.
The device tree clock registration is enabled only if common clk is
selected. Else the old clk registration is been done during
at91_dt_initialize call.

As multiplatform build is being adopted by more and more
ARM platforms, initcall function should be used very carefully.
For example, when SPEAr cpufreq driver is enabled on a kernel
booted on a non-SPEAr board, we will get following boot time error:
spear_cpufreq: Invalid cpufreq_tbl
To eliminate this undesired the effect, the patch changes SPEAr
driver to have it instantiated as a platform_driver. Then it will
only run on platforms that create the platform_device "spear-cpufreq".
This patch also creates platform node for SPEAr13xx boards.

The timer frequency of the arm_global_timer depends on the CPU
frequency. With cpufreq altering that frequency the arm_global_timer
does not maintain a stable time base. Therefore don't enable that timer
in case cpufreq is enabled.
