OMAP4: Add EMIF driver support
This patch adds EMIF driver registration support with hwmod. This patch adds auto-generated header files for EMIF and DMM IP blocks. The scripts are updated accordingly We now have a set of APIs for: Add a set of APIs for the following: 1. Calculating the values of emif configuration registers based on the organization of memory in the device, the AC timing parameters of the memory device, data from JESD209-2 - the LPDDR2 spec, and the frequency at which the LPDDR2 interface is operating. 2. Updating the EMIF settings on: a. frequency change b. voltage ramp c. temperature change OMAP4 EMIF driver also supports the lppddr2 thermal management support as expected by JEDEC standards.
