acpi: add device tree attributes from _CLS if available

means B_DEVICE_TYPE, B_DEVICE_SUB_TYPE, B_DEVICE_INTERFACE.
_CLS is rare, it means I don't own devices with this attribute.

from the spec: _CLS:
Class Code – supplies OSPM with the PCI-defined class, subclass and programming interface for a device. Optional.

Use 64 bit addressing for ACPI on 32 bit builds.

32 bit builds with PAE are so much fun. It's like
64 bit without all the extra registers...

Add get_name and fix get_next_object.

TODO: Need to add defines or enum for nameType.

Add function to walk through children.

Without losing my sanity that is.
ACPI API refactoring will happen some day.

acpi: EcGpeHandler() should return ACPI_REENABLE_GPE.

* this clears the GPE if level triggered and possibly enables the GPE.
See AcpiEvFinishGpe() and AcpiEvGpeDispatch().

acpi: use acpi_event_handler instead of interrupt_handler.

acpi: switch acpi_object from a struct to a union

Update to ACPICA 20121018.

This is an update from 20120711 and A LOT has happened since then. See
https://acpica.org/download/changes.txt for all the changes.

Fixes to Haiku specific code to work with ACPICA 20120711.

* Updated ACPICA to 20110623.
See http://www.acpica.org/download/changes.txt done after 2010-10-13 for info on ACPI changes.
* Adapted the embedded controller to match current FreeBSD one.

There will probably be some issues with these changes initially.

Make the signature argument to get_table() const. Should fix the GCC4 build.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41433 a95241bf-73f2-0310-859d-f6bbb57e9c96

Provide a function to gain ACPI table access.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41429 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add missing const to the path argument of get_handle().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41398 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add set_current_resources() which will be used to configure device resources
from settings retrieved through get_{current|possible}_resources().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41382 a95241bf-73f2-0310-859d-f6bbb57e9c96

Basically revert r41365. Remove the get_pci_info() function of ACPI again as it
turns out to be flaky, is a little bit of a hack anyway and performs unnecessary
operations. The functionality is now handled kernel side which optimizes those
problems away.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41372 a95241bf-73f2-0310-859d-f6bbb57e9c96

Cleanup spaces vs. tabs. Probably those spaces were copied over from ACPICA
sources as they use 4 spaces instead of tabs.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41366 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add a way to look up basic PCI info for an ACPI device. It works for retrieving
the base bus number and segment which is what we're using them for. It should
work generically, however I only tested it to look up PCI bridge devices.
The logic is a subset of what is done in AcpiEvPciConfigRegionSetup when setting
up the operation region for a PCI device.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41365 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The integer type is actually 64bit, probably just a typo (from very long ago).
* Some automatic whitespace cleanup.

This makes the interrupt model change via kernel actually work.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41340 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Disable old embedded controller and remove it from image.
* Move embedded controller code to busmanager module.
* Remove (some) code duplication

Should work as before, but is now initialized right after the bus manager. Can probably remove further code duplication.
I hope I've done it correctly, feedback is most welcome.

Some corrections and cleanup to ACPI Embedded controller:
* Exposed ACPI API needed by Embedded Controller
This will be removed again if moved inside the bus manager.
It also duplicates ACPI's own headers so it might go out of sync atm.
* Added mutex to controller and fixed the mixup between acpi_status needed in int handlers and Haiku status.
* Major code cleanup
Not for headers as they are mostly redundant if we move the controller.
Variable names still needs some cleanup

This makes the ACPI errors from the controller understandable. I get AE_NO_HARDWARE_RESPONSE now.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@11891 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added basic (i.e. argumentless) control method execution. Now we can read fan speeds, cpu temperatures, laptop lid states, and all sorts of other glorious things.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11540 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now we have a nice structure for handling ACPI fixed events. This means we can do things like make acpi_button block, instead of polling it. Direct register access has gone away. The next revision of the bus manager interface should include namespace traversal and AML control method execution.

acpi now uses a simple pci layer instead of the pci bus manager
added a new style module to publish acpi devices ("listdev -d" to list them)

* acpi bus_manager addition of get_object() functions.
* thermal driver uses get_object to obtain the passive device package.

Need changes to acpi_object_type to handle references... that'll have to come in the near future.

Upgraded the bus manager interface. It's now capable enough to start actually doing interesting things, like power management, thermal stuff, and hyperthreading.

Added basic (i.e. argumentless) control method execution. Now we can read fan speeds, cpu temperatures, laptop lid states, and all sorts of other glorious things.

ACPI bus manager interface, revision 3. Now allows full namespace traversal. Next is AML control method execution.

Now we have a nice structure for handling ACPI fixed events. This means we can do things like make acpi_button block, instead of polling it. Direct register access has gone away. The next revision of the bus manager interface should include namespace traversal and AML control method execution.

ACPI Bus Manager interface header. Currently highly incomplete.
