[PATCH 0/5] Eliminate of_platform_bus_type

[PATCH 0/5] Eliminate of_platform_bus_type

[Grant Likely]

This series eliminates the OF platform bus type and moves all users over
to the platform bus.  There is still work to be done to remove the
of_platform_driver references the affected drivers and then remove the
transitional code, but with this series those changes can be done piecewise.

These changes have been tested on PowerPC and UltraSparc.  Microblaze
has only been compile tested (at least by me, but they've been in my test
branch for a long time now, so Michal may have given them a spin.

This series depends on my next-devicetree[1] branch which is also in
linux-next.  I'm pushing them out to my experimental[2] branch for testing
now, and I'll add them to next-devicetree next week unless I hear
otherwise.

David, you'll also want to take a look at patches 4 & 5 to see if you
agree with my decisions on where I move symbols in the header files.

Cheers,
g.

[PATCH 1/5] drivercore/of: Add OF style matching to platform bus

[Grant Likely]

As part of the merge between platform bus and of_platform bus, add the
ability to do of-style matching to the platform bus.

[PATCH 2/5] of: Merge of_platform_bus_type with platform_bus_type

[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.

[PATCH 3/5] of/platform: remove all of_bus_type and of_platform_bus_type references

[Grant Likely]

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.

[PATCH 4/5] of: remove asm/of_platform.h

[Grant Likely]

Only thing left in it is of_instantiate_rtc() which can be moved to
asm/prom.h on PowerPC and is unused in microblaze.

[PATCH 5/5] of: remove asm/of_device.h

[Grant Likely]

It is mostly unused now.  Sparc has a few defines left in it, but they
can be moved to other headers.  Removing this header means that new
architectures adding CONFIG_OF support don't need to also add this
header file.

I think you need to also change this comment, you can't have two
"firsts" :)

If you do that, feel free to add an:
