> of_platform_bus was being used in the same manner as the platform_bus.
> The only difference being that of_platform_bus devices are generated
> from data in the device tree, and platform_bus devices are usually
> statically allocated in platform code.  Having them separate causes
> the problem of device drivers having to be registered twice if it
> was possible for the same device to appear on either bus.
> 
> This patch removes of_platform_bus_type and registers all of_platform
> bus devices and drivers on the platform bus instead.  A previous patch
> made the of_device structure an alias for the platform_device structure,
> and a shim is used to adapt of_platform_drivers to the platform bus.
> 
> After all of of_platform_bus drivers are converted to be normal platform
> drivers, the shim code can be removed.
