arm/dts: Add OMAP2420 H4 support
v3 cover arm/dts: Add OMAP2420 H4 support
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

PATCH RESEND v3 1/2 arm/dts: OMAP2: Add support for OMAP2420H4 Board
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.

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.
