Olof Johansson 01758fe655 Omap5 SoC data via Paul Walmsley <paul@pwsan.com: 
Add support for the OMAP5 SoC family.
 
 As part of the transition to DT, no board files will be used
 for OMAP5.  The hwmod data is gradually being transitioned
 away from arch/arm/mach-omap2: IRQ, DMA, and memory map data
 has been moved to DT.  Hopefully the dev_attr and clock role
 data will be the next step.
 
 Basic test logs are available here, although not for OMAP5,
 since I don't have an OMAP5 board:
