powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where  was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

[POWERPC] Move of_device_get_modalias to drivers/of

2008-05-16T13:22:28+00:00

Commit 140b932f8cb6cced10b96860651a198b1b89cbb9 ("Create modalias file
in sysfs for of_platform bus") needs this to avoid breaking the sparc
builds.

Just move the code and add whitespace around some binary operators.

[POWERPC] Move of_device allocation into of_device.[ch]

2007-10-17T12:30:07+00:00

Extract generic of_device allocation code from of_platform_device_create()
and move it into of_device.[ch], called of_device_alloc(). Also, there's now
of_device_free() which puts the device node.

This way, bus drivers that build on of_platform (like ibmebus will) can
build upon this code instead of reinventing the wheel.

Driver core: change add_uevent_var to use a struct

2007-10-12T21:51:01+00:00

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

Begin consolidation of of_device.h

2007-07-20T03:41:56+00:00

This just moves the common stuff from the arch of_device.h files to
linux/of_device.h.

[POWERPC] Export of_device_get_modalias

2007-05-07T10:31:15+00:00

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 ...

[POWERPC] Add a unified uevent handler for bus based on of_device

2007-04-12T17:55:13+00:00

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.

[POWERPC] Refactor 64 bits DMA operations

2006-12-04T09:38:40+00:00

This patch completely refactors DMA operations for 64 bits powerpc. 32 bits
is untouched for now.

We use the new dev_archdata structure to add the dma operations pointer
and associated data to struct device. While at it, we also add the OF node
pointer and numa node. In the future, we might want to look into merging
that with pci_dn as well.

The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced
by a set of generic iommu and direct DMA ops (non PCI specific) that can be
used by bus types. The toplevel implementation is now inline.

[POWERPC] Souped-up of_platform_device support

2006-12-04T05:08:52+00:00

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.
