The CAPACITY_LEVEL stuff defines various levels of charge; however, what
is the difference between them? What differentiates between HIGH and NORMAL,
LOW and CRITICAL, etc?
As it appears that these are fairly arbitrary, we end up making such policy
decisions in the kernel (or in hardware). This is the sort of decision that
should be made in userspace, not in the kernel.
If the hardware does not support _CAPACITY and it cannot be easily calculated,
then perhaps the driver should register a custom CAPACITY_LEVEL attribute;
however, userspace should not become accustomed to looking for such a thing,
and we should certainly not encourage drivers to provide CAPACITY_LEVEL
stubs.
The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL. The
OLPC battery driver is the only driver making use of this, so it's
removed from there as well.

The execution of ACPI global control methods _GTS and _BFS is
currently tied to the preparation to enter a sleep state and to the
leaving of the sleep state, respectively. However, these functions
are called before disabling the nonboot CPUs and after enabling
them, respectively (in fact, on ACPI 1.0x systems the first of them
ought to be called before suspending devices), while according to the
ACPI specification, _GTS is to be executed right prior to entering
the system sleep state and _BFS is to be executed right after the
platfor firmware has returned control to the OS on wake up.
Move the execution of _GTS and _BFS to the right places.

On ACPI systems the target state set by acpi_pm_set_target() is
reset by acpi_pm_finish(), but that need not be called if the
suspend fails. All platforms that use the .set_target() global
suspend callback are affected by analogous issues.
For this reason, we need an additional global suspend callback that
will reset the target state regardless of whether or not the suspend
is successful. Also, it is reasonable to rename the .set_target()
callback, since it will be used for a different purpose on ACPI
systems (due to ACPI 1.0x code ordering requirements).
Introduce the global suspend callback .end() to be executed at the
end of the suspend sequence and rename the .set_target() global
suspend callback to .begin().

This moves the pci_bus class device to be a real struct device and at
the same time, place it in the device tree in the correct location.
Note, the old "bridge" symlink is now gone, but this was a non-standard
link and no userspace program used it. If you need to determine the
device that the bus is on, follow the standard device symlink, or walk
up the device tree.

PCI Express ASPM defines a protocol for PCI Express components in the D0
state to reduce Link power by placing their Links into a low power state
and instructing the other end of the Link to do likewise. This
capability allows hardware-autonomous, dynamic Link power reduction
beyond what is achievable by software-only controlled power management.
However, The device should be configured by software appropriately.
Enabling ASPM will save power, but will introduce device latency.
This patch adds ASPM support in Linux. It introduces a global policy for
ASPM, a sysfs file /sys/module/pcie_aspm/parameters/policy can control
it. The interface can be used as a boot option too. Currently we have
below setting:
-default, BIOS default setting
-powersave, highest power saving mode, enable all available ASPM
state
and clock power management
-performance, highest performance, disable ASPM and clock power
management
By default, the 'default' policy is used currently.
In my test, power difference between powersave mode and performance mode
is about 1.3w in a system with 3 PCIE links.

The function pci_osc_support_set() traverses every root bridge when
checking for _OSC support for a capability. It quits as soon as it finds a
device/bridge that doesn't support the requested capability. This won't
work for systems that have mixed PCI and PCIe bridges when checking for
PCIe features. I split this function into two -- pci_osc_support_set() and
pcie_osc_support_set(). The latter is used when only PCIe devices should be
traversed.

The pci_enable_device_bars() interface isn't well suited to PCI
because you can't actually enable/disable BARs individually on
a device. So for example, if a device has 2 memory BARs 0 and 1,
and one of them (let's say 1) has not been successfully allocated
by the firmware or the kernel, then enabling memory decoding
shouldn't be permitted for the entire device since it will decode
whatever random address is still in that BAR 1.
So a device must be either fully enabled for IO, for Memory, or
for both. Not on a per-BAR basis.
This provides two new functions, pci_enable_device_io() and
pci_enable_device_mem() to replace pci_enable_device_bars(). The
implementation internally builds a BAR mask in order to be able
to use existing arch infrastructure.

The current pci_assign_unassigned_resources() code doesn't work properly
on 32 bits platforms with 64 bits resources. The main reason is the use
of unsigned long in various places instead of resource_size_t.
This is a pre-requisite for making powerpc use the generic code instead of
its own half-useful implementation.

PCI error recovery usually involves the PCI adapter being reset.
If the device is using MSI, the reset will cause the MSI state
to be lost; the device driver needs to restore the MSI state.

by CONFIG_PM; remove this, and also export the symbol, so
that it can be used in a modle.

Various small at91_udc cleanups:
- Use generic GPIO calls, not older platform-specific ones
- Use gpio_request()/gpio_free()
- Use VERBOSE_DEBUG convention, not older VERBOSE
- Fix sparse complaint about parameter type (changed to gfp_t)
- Add missing newline to some rarely-seen debug messages
- Fix some old cleanup bugs on probe() fault paths
Also add a mechanism whereby rm9200 gpios can drive the D+ pullup
through an inverting transistor, based on a patch from Steve Birtles.
Most UDC drivers supporting a GPIO based pullup should probably have

This patch exports two statistics to userspace:
/sys/bus/usb/device/.../power/connected_duration
/sys/bus/usb/device/.../power/active_duration
connected_duration is the total time (in msec) that the device has
been connected. active_duration is the total time the device has not
been suspended. With these two statistics, tools like PowerTOP can
calculate the percentage time that a device is active, i.e. not
suspended or auto-suspended.
Users can also use the active_duration to check if a device is actually
autosuspended. Currently, they can set power/level to auto and
power/autosuspend to a positive timeout, but there's no way to know from
userspace if a device was actually autosuspended without looking at the
dmesg output. These statistics will be useful in creating an automated
userspace script to test autosuspend for USB devices.

When a usb serial adapter is used as console, the usb serial console
driver bumps the open_count on the port struct used but doesn't attach
a real tty to it (only a fake one temporaly). If this port is opened later
using the regular character device interface, the open method won't
initialize the port, which is the expected, and will receive a brand new
tty struct created by tty layer, which will be stored in port->tty.
When the last close is issued, open_count won't be 0 because of the
console usage and the port->tty will still contain the old tty value. This
is the last ttyUSB<n> close so the allocated tty will be freed by the
tty layer. The usb_serial and usb_serial_port are still in use by the
console, so port_free() won't be called (serial_close() ->
usb_serial_put() -> destroy_serial() -> port_free()), so the scheduled
work (port->work, usb_serial_port_work()) will still run. And
usb_serial_port_work() does:
(...)
tty = port->tty;
if (!tty)
return;
tty_wakeup(tty);
which causes (manually copied):

* Make ide_build_sglist() and ide_destroy_dmatable() available also when
CONFIG_BLK_DEV_IDEDMA_PCI=n.
* Use ide_build_sglist() and ide_destroy_dmatable() in {ics,au1xxx-}ide.c
and remove no longer needed {ics,au}ide_build_sglist().
There should be no functionality changes caused by this patch.

Keep pointer to struct device instead of struct pci_dev in ide_hwif_t.
While on it:
* Use *dev->dma_mask instead of pci_dev->dma_mask in ide_toggle_bounce().
There should be no functionality changes caused by this patch.

* Add IDE_HFLAG_NO_DSC host flag for hosts that doesn't support DSC overlap.
* Set it in aec62xx (for ATP850UF only) and hpt34x host drivers.
* Convert ide-tape device driver to check for IDE_HFLAG_NO_DSC flag.

* Rename 'simplex_stat' variable to 'dma_stat' in ide_get_or_set_dma_base().
* Factor out code for forcing host out of "simplex" mode from
ide_get_or_set_dma_base() to ide_pci_clear_simplex() helper.
* Add IDE_HFLAG_CLEAR_SIMPLEX host flag and set it in alim15x3 (for M5229),
amd74xx (for AMD 7409), cmd64x (for CMD643), generic (for Netcell) and
serverworks (for CSB5) host drivers.
* Make ide_get_or_set_dma_base() test for IDE_HFLAG_CLEAR_SIMPLEX host flag
instead of checking dev->device (BTW the code was buggy because it didn't
check for dev->vendor, luckily none of these PCI Device IDs was used by
some other vendor for PCI IDE controller).

According to http://marc.info/?l=linux-ide&m=114346138611631, the drivers must
always register 8 DMA ports with ide_setup_dma(), so its last argument is not
needed. While at it, kill some useless parens in that function...

* Add ide_dump_identify() debug helper for dumping raw identify data in
the hdparm friendly format (== the identify data can be extracted from
dmesg output and passed to hdparm --Istdin).
* Dump identify data in ide-probe.c::do_identify() if DEBUG is enabled.
