of: Merge of_platform_bus_type with platform_bus_type 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. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

Also replace to_of_device() with to_platform_device() and update comment blocks.

dt: eliminate of_platform_driver shim code Commit eca393016, "of: Merge of_platform_bus_type with platform_bus_type" added a shim to allow of_platform_drivers to get registers onto the platform bus so that there was time to migrate the existing drivers to the platform_bus_type. This patch removes the shim since there are no more users of the old interface. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
