Here are more patches in the progression towards multiplatform, sparse
irq conversions in particular.
Tegra has a handful of cleanups and general groundwork, but is
not quite there yet on full enablement.
Platforms that are enabled through this branch are VT8500 and Zynq. note
that i.MX was converted in one of the earlier cleanup branches as
well (before we started a separate topic for multiplatform). And both
new platforms for this merge window, sunxi and bcm, were merged with
multiplatform support enabled.

many drivers have already been converted. It has been in linux-next
for a couple of weeks and there have been no major issues so I think
it is ready for inclusion in your tree."
Arnd Bergmann <arnd@arndb.de>:
"Very much Ack on the new subsystem. It uses the interface
declarations as the previously separate pwm drivers, so nothing
changes for now in the drivers using it, although it enables us to
change those more easily in the future if we want to.
This work is also one of the missing pieces that are required to
eventually build ARM kernels for multiple platforms, which is
currently prohibited (amongs other things) by the fact that you cannot
have more than one driver exporting the pwm functions."

In tegra*.dtsi, set status="disable" for all HW modules that the board

Sort the nodes according to the following rules:
* First, any overrides for properties or nodes created by included files,
in the order they appeared in the include file.
* Second, any nodes with a reg property, in numerical order.
* Third, any nodes without a reg property, in alphabetical order of node
name.
The second sorting rule at least will probably help if/when we need to
explicitly insert nodes for the various busses in Tegra; that will just
be an indentation change rather than also a node re-ordering.

any device tree node interrupts properties are correctly parsed.
