This series fixes the OMAP2 interrupt controller binding and adds support for
the OMAP2420 H4 board. I have verified that the kernel boots with device-tree
on this board.
This series is based upon the linux-omap master branch (3.5-rc1).
V3: Rename OMAP2420 SDP to OMAP2420 H4
V2: Correct typo in copyright date

Simple DTS file for OMAP2420H4 board adding memory information to allow
device-tree testing on an OMAP2420. OMAP2420H4 board has 64MB of RAM.
Verified that kernel boots with DT using a simple RAMDISK file-system on
OMAP2420H4.

Thanks, applying into dt branch.

When booting with device-tree on an OMAP2420H4, the kernel is hanging when
initialising the interrupts and following kernel dumps is seen ...

The OMAP2 interrupt controller binding is missing the number of interrupts and
interrupt controller register address. Adding these fixes the problem.
This is based upon latest linux-omap master (3.5-rc1) git tree.

Thanks this is a good one, applying into fixes.
