David Brownell 55955aad7c PNPACPI sets pnpdev->dev.archdata
Teach PNPACPI how to hook up its devices to their ACPI nodes, so that
pnpdev->dev.archdata points to the parallel acpi device node.  Previously
this only worked for PCI, leaving a notable hole.

Export "acpi_bus_type" so this can work.

Remove some extraneous whitespace.

Greg Kroah-Hartman 823bccfc40 remove "struct subsystem" as it is no longer needed
We need to work on cleaning up the relationship between kobjects, ksets and
ktypes.  The removal of 'struct subsystem' is the first step of this,
especially as it is not really needed at all.

Thanks to Kay for fixing the bugs in this patch.

Zhang Rui bb0958544f ACPI: use more understandable bus_id for ACPI devices
Some of the ACPI devices use the internal fake hids
which are exposed to userspace as devces' bus_id after sysfs conversion.
To make it more friendly, we convert them to more understandable strings.

For those devices w/o PNPids, we use "device:instance_no" as the bus_id
instead of "PNPIDNON:instance_no".

Zhang Rui ae8433324b ACPI: Set fake hid for non-PNPID ACPI devices
We do this mainly because:
1.	hid is used to match ACPI devices and drivers.
	.match method which is incompatible to driver model
	can be deleted from acpi_driver.ops then.
2.	As the .uevent method mark ACPI drivers by PNPID,
	fake hid is set to non-PNPID devices so that udev script
	can load the right ACPI driver by looking for
	"HWID = " or "COMPTID = ".

Add removal_type in structure acpi_device for hot removal.

ACPI_BUS_REMOVAL_EJECT is used for ACPI device hot removal.
Only one parameter is allowed in .remove method due to driver model.
So removal_type is added to indicate different removal type.

Li Shaohua c4168bff32 ACPI: add acpi_bus_ops in acpi_device
Add acpi_bus_ops in acpi_device to support acpi hot plug.

NOTE:	Two methods .add and .start in acpi_driver.ops are
	called separately to probe ACPI devices, while only
	.probe method is called in driver model.
	As executing .add and .start separately is critical
	for ACPI device hot plug, we use acpi_bus_ops to
	distinguish different code path.

Patrick Mochel f883d9db00 ACPI: convert to sysfs framework
Setup new sysfs framework

1.	Remove /sys/firmware/acpi
2.	Add ACPI device in device tree.

File "eject" for every device that has _EJ0 method is moved from
/sys/firmware to /sys/devices.
Operation on this file is exactly the same as before.
i.e. echo 1 to "eject" will cause hot removal of this device.
Corresponding changes should be made in userspace for hot removal.

Change ACPI to use dev_archdata instead of firmware_data

This patch changes ACPI to use the new dev_archdata on i386, x86_64
and ia64 (is there any other arch using ACPI ?) to store it's
acpi_handle.

It also removes the firmware_data field from struct device as this
was the only user.

Only build-tested on x86

Bob Moore 793c2388ca ACPI: ACPICA 20060331
Implemented header file support for the following
additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR,
SPMI, TCPA, and WDRT. With this support, all current and
known ACPI tables are now defined in the ACPICA headers and
are available for use by device drivers and other software.

Implemented support to allow tables that contain ACPI
names with invalid characters to be loaded. Previously,
this would cause the table load to fail, but since
there are several known cases of such tables on
existing machines, this change was made to enable
ACPI support for them. Also, this matches the
behavior of the Microsoft ACPI implementation.
https://bugzilla.novell.com/show_bug.cgi?id=147621

Fixed a couple regressions introduced during the memory
optimization in the 20060317 release. The namespace
node definition required additional reorganization and
an internal datatype that had been changed to 8-bit was
restored to 32-bit. (Valery Podrezov)

Fixed a problem where a null pointer passed to
acpi_ut_delete_generic_state() could be passed through
to acpi_os_release_object which is unexpected. Such
null pointers are now trapped and ignored, matching
the behavior of the previous implementation before the
deployment of acpi_os_release_object().  (Valery Podrezov,
Fiodor Suietov)

Fixed a memory mapping leak during the deletion of
a SystemMemory operation region where a cached memory
mapping was not deleted. This became a noticeable problem
for operation regions that are defined within frequently
used control methods. (Dana Meyers)

Reorganized the ACPI table header files into two main
files: one for the ACPI tables consumed by the ACPICA core,
and another for the miscellaneous ACPI tables that are
consumed by the drivers and other software. The various
FADT definitions were merged into one common section and
three different tables (ACPI 1.0, 1.0+, and 2.0)

Bjorn Helgaas 06ea8e08ae ACPI: acpi_bus_unregister_driver() returns void
Nobody looks at the return value, and this brings it into line with
pci_unregister_driver(), etc.  Also removed validation of the driver
pointer passed in to register and unregister.  More consistent, and we'll
find bugs faster if we fault rather than returning an error that's ignored.

Also makes internal functions acpi_device_unregister() and
acpi_driver_detach() void, since nobody uses their returns either.

David Shaohua Li 4e10d12a3d [ACPI] Bind PCI devices with ACPI devices
Implement the framework for binding physical devices
with ACPI devices. A physical bus like PCI bus
should create a 'acpi_bus_type', with:

.find_device:
        For device which has parent such as normal PCI devices.

.find_bridge:
        It's for special devices, such as PCI root bridge
	or IDE controller.  Such devices generally haven't a
	parent or ->bus. We use the special method
	to get an ACPI handle.

Uses new field in struct device: firmware_data

Create new interfaces to recursively add an acpi namespace object to the acpi
device list, and recursively start the namespace object.  This is needed for
ACPI based hotplug of a root bridge hierarchy where the add operation must be
performed first and the start operation must be performed separately after the
hot-plugged devices have been properly configured.

Initial git repository build. I'm not bothering with the full history,

archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
