de41189bf6 [POWERPC] Export of_device_get_modalias
Apparently other parts of the kernel need to know the
modalias internally (like the sysfs code in macintosh driver).

To avoid consistency issues, we export this code and use it
everywhere it's needed rather than repeat it ...

55b61fec22 [POWERPC] Rename device_is_compatible to of_device_is_compatible
for consistency with other Open Firmware interfaces (and Sparc).

This is just a straight replacement.

This leaves the compatibility define in place.

eb0cb8a07e [POWERPC] Add a unified uevent handler for bus based on of_device
This common uevent handler allow the several bus types based on
of_device to generate the uevent properly and avoiding
code duplication.

This handlers take a struct device as argument and can therefore
be used as the uevent call directly if no special treatment is
needed for the bus.

7eebde700f [POWERPC] Souped-up of_platform_device support
This patch first splits of_device.c and of_platform.c, the later containing
the bits relative to of_platform_device's. On the "breaks" side of things,
drivers uisng of_platform_device(s) need to include asm/of_platform.h now
and of_(un)register_driver is now of_(un)register_platform_driver.

In addition to a few utility functions to locate of_platform_device(s),
the main new addition is of_platform_bus_probe() which allows the platform
code to trigger an automatic creation of of_platform_devices for a whole
tree of devices.

The function acts based on the type of the various "parent" devices encountered
from a provided root, using either a default known list of bus types that can be
"probed" or a passed-in list. It will only register devices on busses matching
that list, which mean that typically, it will not register PCI devices, as
expected (since they will be picked up by the PCI layer).

This will be used by Cell platforms using 4xx-type IOs in the Axon bridge
and can be used by any embedded-type device as well.

980ffd3258 [POWERPC] Remove linux,device properties
The linux,device property isn't used anywhere within the kernel, and
since it's a kernel pointer, it's a little useless for userspace.

This change removes the code to create this property in
of_device_register.

Built for pmac32.

6ea671a12f [PATCH] powerpc: tidy-up of_register_driver()/driver_register() return values
Remove the assumption that driver_register() returns the number of devices
bound to the driver.  In fact, it returns zero for success or a negative
error value.

Nobody uses the return value of of_register_driver() anyway.
