[PATCH V3 0/3] ARM: dts: omap5: EMIF and LPDDR2 device tree data

[Lokesh Vutla]

This patch series adds Device tree data for the EMIF 
sdram controllers in OMAP5 and LPDDR2 memory devices 
in OMAP5-evm board.

Testing:
- Boot tested on OMAP5430 evm.
- Built EMIF as a module.

Changes from v2:
* Rebased on top of
  git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt.git for_3.8/dts
* Addressed few other comments from Benoit.

[PATCH V3 1/3] ARM: dts: omap5-evm: Fix size of memory defined for EVM

[Lokesh Vutla]

Memory present for OMAP5-evm is 2GB. But in dts file
it is specified as 1GB. Correcting the same.

Thanks for this quick update.
I've just applied your series in my for_3.8/dts_part2 branch.
