The first patch adds bindings for DDR memories. Currently, we have added properties for only DDR3 and LPDDR2 memories. However, the binding can be easily extended to describe other types such as DDR2 in the future. The second patch provides the bindings for the EMIF controller. The final patch provides DT data for EMIF controller instances in OMAP4 and LPDDR2 memories attached to them on various boards. Thanks to Rajendra for answering my numerous queries on device tree.
