Merge branch 'irqchip-consolidation' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into devel-stable

Conflicts:
	arch/arm/mach-omap2/board-4430sdp.c
	arch/arm/mach-omap2/board-omap4panda.c
	arch/arm/mach-omap2/include/mach/omap4-common.h
	arch/arm/plat-omap/include/plat/irqs.h

The changes to omap4-common.h were moved to arch/arm/mach-omap2/common.h
and the other trivial conflicts resolved.  The now empty ifdef in irqs.h
was also eliminated.

* ARM Vectored Interrupt Controller
One or more Vectored Interrupt Controllers (VIC's) can be connected in an ARM
system for interrupt routing. For multiple controllers they can either be
nested or have the outputs wire-OR'd together.
Required properties:
- compatible : should be one of
"arm,pl190-vic"
"arm,pl192-vic"
- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : The number of cells to define the interrupts. Must be 1 as
the VIC has no configuration options for interrupt sources. The cell is a u32
and defines the interrupt number.
- reg : The register bank for the VIC.
Optional properties:
- interrupts : Interrupt source for parent controllers if the VIC is nested.
Example:
vic0: interrupt-controller@60000 {
compatible = "arm,pl192-vic";
interrupt-controller;
#interrupt-cells = <1>;
reg = <0x60000 0x1000>;

* Interrupts 0-15 are IPI
* 16-28 are reserved
* 29-31 are local. We allow 30 to be used for the watchdog.
* 32-1020 are global
* 1021-1022 are reserved
* 1023 is "spurious" (no interrupt)
*
* For now, we ignore all local interrupts so only return an interrupt if it's
* between 30 and 1020. The test_for_ipi routine below will pick up on IPIs.
*
* A simple read from the controller will tell us the number of the highest
* priority enabled interrupt. We then just need to check whether it is in the
