      of/device: Merge of_platform_bus_probe() · 5fd200f3
      Grant Likely authored 
      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.

      of: Modify of_device_get_modalias to be passed struct device · 34a1c1e8
      Grant Likely authored 
      Now that the of_node pointer is part of struct device,
of_device_get_modalias could be used on any struct device
that has the device node pointer set.  This patch changes
of_device_get_modalias to accept a struct device instead
of a struct of_device.

      of: Use full node name in resource structures · d3571c3a
      Grant Likely authored 
      Resource names appear in human readable output, so when extracting IRQ
and address resources from a device tree node, use the full node name
to give proper context in places like /proc/iomem.

      Certain Apple machines don't use the ranges property correctly, but the
workaround should not be applied on other architectures.  This patch

      of/address: Merge all of the bus translation code · dbbdee94
      Grant Likely authored 
      Microblaze and PowerPC share a large chunk of code for translating
OF device tree data into usable addresses.  Differences between the two
consist of cosmetic differences, and the addition of dma-ranges support
code to powerpc but not microblaze.  This patch moves the powerpc
version into common code and applies many of the cosmetic (non-functional)
changes from the microblaze version.

      of/irq: merge irq mapping code · 7dc2e113
      Grant Likely authored 
      Merge common irq mapping code between PowerPC and Microblaze.

This patch merges of_irq_find_parent(), of_irq_map_raw() and
of_irq_map_one().  The functions are dependent on one another, so all
three are merged in a single patch.  Other than cosmetic difference
(ie. DBG() vs. pr_debug()), the implementations are identical.

of_irq_to_resource() is also merged, but in this case the
implementations are different.  This patch drops the microblaze version
and uses the powerpc implementation unchanged.  The microblaze version
essentially open-coded irq_of_parse_and_map() which it does not need
to do.  Therefore the powerpc version is safe to adopt.

      of/powerpc: Move Powermac irq quirk code into powermac pic driver code · b83da291
      Grant Likely authored 
      The code that figures out what is wrong with the powermac irq device
tree data belongs with the rest of the powermac irq code.  This patch
moves it out of prom_parse.c and into powermac/pic.c so that it is only
compiled in when actually needed.

      of: kill struct of_device · b505ff5e
      Grant Likely authored 
      Now that the device tree node pointer has been moved out of struct
of_device and into the common struct device, there isn't anything
unique about of_device anymore.  In fact, there isn't much need
for a separate of_bus when all busses have access to OF style
probing.

arch/powerpc and arch/microblaze are moving away from using the of_bus
and using the regular platform bus instead for mmio devices.  This
patch makes of_device the same as platform_device as a stepping stone
in migrating of_platform_drivers over to the platform bus.

      sparc/of: Move of_device fields into struct pdev_archdata · 1636f8ac
      Grant Likely authored 
      This patch moves SPARC architecture specific data members out of
struct of_device and into the pdev_archdata structure.  The reason
for this change is to unify the struct of_device definition amongst
all the architectures.  It also remvoes the .sysdata, .slot, .portid
and .clock_freq properties because they aren't actually used by
anything.

A subsequent patch will replace struct of_device entirely with struct
platform_device and the of_platform support code will share common
routines with the platform bus (but the bus instances themselves can
remain separate).

This patch also adds 'struct resources *resource' and num_resources
to match the fields defined in struct platform_device.  After this
change, 'struct platform_device' can be used as a drop-in replacement
for 'struct of_platform'.

This change is in preparation for merging the of_platform_bus_type
with the platform_bus_type.
