There is nothing modular in this file, and no reason to drag
in all the 357 headers that module.h brings with it, since
it just slows down compiles.Signed-off-by: Paul Gortmaker

Some platform code has specific requirements on the naming of devices.
This patch allows callers of of_platform_populate() to provide a
device name lookup table.Signed-off-by: Grant Likely

of_platform_populate() is similar to of_platform_bus_probe() except
that it strictly enforces that all device nodes must have a compatible
property, and it can be used to register devices (not buses) which are
children of the root node.Signed-off-by: Grant Likely

No need for most platforms to define their own bus table when calling
of_platform_populate(). Supply a stock one.Signed-off-by: Grant Likely

There are no users of OF_NO_DEEP_PROBE, and of_match_node() now
gracefully handles being passed a NULL pointer, so the checks at the
top of of_platform_bus_probe can be dropped.While at it, consolidate the root node pointer check to be easier to
read and tidy up related comments.Signed-off-by: Grant Likely

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

arch/powerpc/kernel/ibmebus.c is the only remaining user of the
of_bus_type support code for initializing the bus and registering
drivers. 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.Signed-off-by: Grant Likely

of_device is just an alias for platform_device, so remove it entirely. Also
replace to_of_device() with to_platform_device() and update comment blocks.This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.@@

This list used was by only two platforms with all other platforms defining an
own list of valid bus id's to pass to of_platform_bus_probe. This patch:i) copies the default list to the two platforms that depended on it (powerpc)
ii) remove the usage of of_default_bus_ids in of_platform_bus_probe
iii) removes the definition of the list from all architectures that defined itPassing a NULL 'matches' parameter to of_platform_bus_probe is still valid; the
function returns no error in that case as the NULL value is equivalent to an
empty list.Signed-off-by: Jonas Bonn
[grant.likely@secretlab.ca: added __initdata annotations, warn on and return error on missing match table, and fix whitespace errors]

Both of_bus_type and of_platform_bus_type are just #define aliases
for the platform bus. This patch removes all references to them and
switches to the of_register_platform_driver()/of_unregister_platform_driver()
API for registering.Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim. At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.Signed-off-by: Grant Likely

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

Merge common code between PowerPC and microblaze. This patch merges
the code that scans the tree and registers devices. The functions
merged are of_platform_bus_probe(), of_platform_bus_create(), and
of_platform_device_create().This patch also move the of_default_bus_ids[] table out of a Microblaze
header file and makes it non-static. The device ids table isn't merged
because powerpc and microblaze use different default data.Signed-off-by: Grant Likely

.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver. This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so
many files, but it should be pretty safe.Signed-off-by: Grant Likely
