This is the basic devicetree support for C6X. Currently, four boards are
supported. Each one uses a different SoC part. Two of the four supported
SoCs are multicore. One with 3 cores and the other with 6 cores. There is
no coherency between the core-level caches, so SMP is not an option. It is
possible to run separate kernel instances on the various cores. There is
currently no C6X bootloader support for device trees so we build in the DTB
for now.
There are some interesting twists to the hardware which are of note for device
tree support. Each core has its own interrupt controller which is controlled
by special purpose core registers. This core controller provides 12 general
purpose prioritized interrupt sources. Each core is contained within a
hardware "module" which provides L1 and L2 caches, power control, and another
interrupt controller which cascades into the core interrupt controller. These
core module functions are controlled by memory mapped registers. The addresses
for these registers are the same for each core. That is, when coreN accesses
a module-level MMIO register at a given address, it accesses the register for
coreN even though other cores would use the same address to access the register
in the module containing those cores. Other hardware modules (timers, enet, etc)
which are memory mapped can be accessed by all cores.
The timers need some further explanation for multicore SoCs. Even though all
timer control registers are visible to all cores, interrupt routing or other
considerations may make a given timer more suitable for use by a core than
some other timer. Because of this and the desire to have the same image run
on more than one core, the timer nodes have a "ti,core-mask" property which
is used by the driver to scan for a suitable timer to use.

Add a notifier called during device_add phase. If an of_node is present,
retrieve the hwmod entry in order to populate properly the omap_device
structure.
For the moment the resource from the device-tree are overloaded.
DT does not support named resource yet, and thus, most driver will not
work without that information.
Add a documentation to capture the specifics OMAP bindings needed for
device-tree support.

There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.
Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

picoXcell is a family of femtocell devices with an ARM application
processor and picoArray DSP processor array.
This patch adds support for picoXcell boards to be booted using the
device tree registering the VIC's, UART's and timers.
v3: - fixup vic compatible string in binding
v2: - cleanup empty mach headers
- convert to of_platform_populate()
- simplify uncompress.h

The Synopsys DesignWare 8250 is an 8250 that has an extra interrupt that
gets raised when writing to the LCR when busy. To handle this we need
special serial_out, serial_in and handle_irq methods. Add a new
platform driver that uses these accessors.

continue as a normal 8250 as we may still get some useful debug out.

For testing the dt work, define a dt-enabled versatile platform.
This patch adds a new versatile platform for when using the device
tree. Add platform and amba devices are discovered and registered by
parsing the device tree. Clocks and initial io mappings are still
configured statically.
This patch still depends on some static platform_data for a few devices
which is passed via the auxdata structure to of_platform_populate(),
but it is a viable starting point until the drivers can get all
configuration data out of the device tree.
