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.

Tony
