c3d6de698c ACPI video: if no ACPI backlight support, use vendor drivers
If an ACPI graphics device supports backlight brightness functions (cmp. with
latest ACPI spec Appendix B), let the ACPI video driver control backlight and
switch backlight control off in vendor specific ACPI drivers (asus_acpi,
thinkpad_acpi, eeepc, fujitsu_laptop, msi_laptop, sony_laptop, acer-wmi).

Currently it is possible to load above drivers and let both poke on the
brightness HW registers, the video and vendor specific ACPI drivers -> bad.

This patch provides the basic support to check for BIOS capabilities before
driver loading time. Driver specific modifications are in separate follow up
patches.

"acpi_backlight=vendor"
	Prever vendor driver over ACPI driver for backlight.
"acpi_backlight=video" (default)
	Prever ACPI driver over vendor driver for backlight.

0794469da3 ACPI: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

ad93a765c1 ACPI: Disambiguate processor declaration type
Declaring processors in ACPI namespace can be done using either a
"Processor" definition or a "Device" definition (see section 8.4 -
Declaring Processors; "Advanced Configuration and Power Interface
Specification", Revision 3.0b).  Currently the two processor
declaration types are conflated.

This patch disambiguates the processor declaration's definition type
enabling subsequent code to behave uniquely based explicitly on the
declaration's type.

39a0ad8710 ACPI : Load device driver according to the status of acpi device
According to ACPI spec when the status of some device is not present
but functional, the device is valid and the children of this device
should be enumerated. It means that the device should be added to
linux acpi device tree. But the device driver for this device should not
be loaded.
    The detailed info can be found in the section 6.3.7 of ACPI 3.0b spec.
    _STA may return bit 0 clear (not present) with bit 3 set (device is
functional). This case is used to indicate a valid device for which no
device driver should be loaded (for example, a bridge device.).
Children of this device may be present and valid. OS should continue
enumeration below a device whose _STA returns this bit combination

power flag is power_managable. i.e. The device has the _PSx/_PRx object.

455c8793d2 ACPI: Enable EC device immediately after ACPI full initialization
when there is no ECDT table and no _INI object for EC device, it will be
enabled before scanning ACPI device. But it is too late after the following
the commit is merged.
    >commit 7752d5cfe3
    > Author: Robert Hancock <hancockr@shaw.ca>
    > Date:   Fri Feb 15 01:27:20 2008 -0800
       >x86: validate against acpi motherboard resources

   After the above commit is merged, OS will check whether MCFG area is
reserved in ACPI motherboard resources by calling the function of
acpi_get_devices when there exists MCFG table. In the acpi_get_devices the _STA
object will be evaluated to check the status of the ACPI device. On some broken
BIOS the MYEC object of EC device is initialized as one, which indicates that
EC operation region is already accessible before enabling EC device.So on these
broken BIOS the EC operation region will be accessed in course of evaluating
the _STA object before enabling EC device, which causes that OS will print the
following warning messages:
    >ACPI Error (evregion-0315): No handler for Region [EC__] (ffff88007f8145e8)
[EmbeddedControl] [20080609]
    >ACPI Error (exfldio-0290): Region EmbeddedControl(3) has no handler [20080321]
    >ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.PCI0.SBRG.
         EC__.BAT1._STA] (Node ffff81013fc17a00), AE_NOT_EXIST
    >ACPI Error (uteval-0233): Method execution failed [\_SB_.PCI0.SBRG.EC__.BAT1.
         _STA] (Node ffff81013fc17a00), AE_NOT_EXIST

Although the above warning message is harmless, it looks confusing.
So it is necessary to enable EC device as early as possible.Maybe it is
appropriate to enable it immediately after ACPI full initialization.

729b2bdbfa ACPI : Disable the device's ability to wake the sleeping system in the boot phase
In some machines some GPE is shared by several ACPI devices, for example:
sleep button, keyboard, mouse. At the same time one of them is
non-wake(runtime) device and the other are wake devices. In such case OSPM
should call the _PSW object to disable the device's ability to
wake the sleeping system in the boot phase.
Otherwise there will be ACPI interrupt flood triggered by the GPE input.

The _PSW object is depreciated in ACPI 3.0 and is replaced by _DSW.
So it is necessary to call _DSW object first. Only when it is not
present will the _PSW object used.

References: https://bugzilla.novell.com/show_bug.cgi?id=302482

Due to the new autloading of acpi drivers, the dock driver
wasn't loaded anymore as there is no HID to identify it with
(dock is needed if ACPI has a  _DCK method).
This patch is a workaround for this, original by Thomas Renninger,
revised first by Kay Sievers and last by Frank Seidel.
V2 of this patch fixed problems on systems without a defined _CID for
the docking devices.

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.

f52fd66d2e ACPI: clean up ACPI_MODULE_NAME() use
cosmetic only

Make "module name" actually match the file name.
Invoke with ';' as leaving it off confuses Lindent and gcc doesn't care.
Fix indentation where Lindent did get confused.
