All others have either been switched to the vanilla platform bus or already have their own infrastructure. This patch moves the functionality that ibmebus is using out of drivers/of/{platform,device}.c and into ibmebus.c where it is actually used. Also renames the moved symbols from of_platform_* to ibmebus_bus_* to reflect the actual usage. This patch is part of moving all of the of_platform_bus_type users over to the platform_bus_type.
