Well the headers in include/linux/platform_data should only
contain platform data passed to the driver. So you should
keep arch/arm/mach-omap2 specific stuff in the local headers,
then have the driver specific stuff private to the drivers,
and then have separate minimal platform data headers.

Please also try to avoid patching all the board-*.c files if
possible by keeping the the local headers in place as the board
files will be going away for v3.14 anyways. You can include
the new platform data header from those local files as that
cuts down extra churn in the board-*.c files a bit ;)
