Pull devicetree updates from Rob Herring:
"DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.

- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to
multiple interrupt controllers.
- Refactoring of DT interrupt parsing code in preparation for
deferred probe of interrupts.
- ARM cpu and cpu topology bindings documentation.
- Various DT vendor binding documentation updates"

of/irq: create interrupts-extended property

2013-10-28T23:48:14+00:00

The standard interrupts property in device tree can only handle
interrupts coming from a single interrupt parent. If a device is wired
to multiple interrupt controllers, then it needs to be attached to a
node with an interrupt-map property to demux the interrupt specifiers
which is confusing. It would be a lot easier if there was a form of the
interrupts property that allows for a separate interrupt phandle for
each interrupt specifier.

This patch does exactly that by creating a new interrupts-extended
property which reuses the phandle+arguments pattern used by GPIOs and
other core bindings.

Documentation: dt: Remove interrupt sources list for Allwinner SoCs

2013-10-11T19:24:43+00:00

That documentation was mostly useful when we didn't have any
documentation for those SoCs, which is not the case anymore. Remove
this, since it should live in the DT anyway.

Pull ARM SoC device tree changes from Arnd Bergmann:
 "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"

ARM: shmobile: irqpin: add a DT property to enable masking on parent

2013-06-19T12:27:31+00:00

To disable spurious interrupts, that get triggered on certain hardware, the
irqpin driver masks them on the parent interrupt controller. To specify
such broken devices a .control_parent parameter can be provided in the
platform data. In the DT case we need a property, to do the same.

irqchip: renesas-intc-irqpin: DT binding for sense bitfield width

2013-06-18T07:15:18+00:00

Most Renesas irqpin controllers have 4-bit sense fields, however, some
have different widths. This patch adds a DT binding to optionally
specify such non-standard values.
