To avoid merge conflicts and dependencies between drivers and core Soc code, please break thes kind of patches into following parts: 1. Any platform_data header changes needed so both I and Tomi can pull it in as needed. 2. Changes to DSS drivers. Please keep stubs around for the board specific callback functions so omap2plus_defconfig won't break with just #1 merged into arm soc tree. 3. All the arch/arm/*omap* changes based on #1 above to drop obsolete callback functions and add new pdata if still needed. This needs to build and boot on #1 so I can merge this in via arm soc tree. 4. Any .dts changes needed.
