Begin to consolidate of_device.c This moves all the common parts for the Sparc, Sparc64 and PowerPC of_device.c files into drivers/of/device.c. Apart from the simple move, Sparc gains of_match_node() and a call to of_node_put in of_release_dev(). PowerPC gains better recovery if device_create_file() fails in of_device_register().

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

of/device: Rework to use common platform_device_alloc() for allocating devices The current code allocates and manages platform_devices created from the device tree manually. It also uses an unsafe shortcut for allocating the platform_device and the resource table at the same time. (which I added in the last rework; sorry). This patch refactors the code to use platform_device_alloc() for allocating new devices. This reduces the amount of custom code implemented by of_platform, eliminates the unsafe alloc trick, and has the side benefit of letting the platform_bus code manage freeing the device data and resources when the device is freed.

OF-device: Don't overwrite numa_node in device registration Currently, the numa_node of OF-devices will be overwritten during device_register, which simply sets the node to -1. On cell machines, this means that devices can't find their IOMMU, which is referenced through the device's numa node. Set the numa node for OF devices with no parent, and use the lower-level device_initialize and device_add functions, so that the node is preserved. We can remove the call to set_dev_node in of_device_alloc, as it will be overwritten during register. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

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.
