This is a refresh of an earlier patch to add "wakeup" support to the
PM core model. This provides per-device bus-neutral control of the
use of wakeup events.
* "struct device_pm_info" has two bits that are initialized as
part of setting up the enclosing struct device:
- "can_wakeup", reflecting hardware capabilities
- "may_wakeup", the policy setting (when CONFIG_PM)
* There's a writeable sysfs "wakeup" file, with one of two values:
- "enabled", when the policy is to allow wakeup
- "disabled", when the policy is not to allow it
- "" if the device can't currently issue wakeups
By default, wakeup is enabled on all devices that support it. If its
driver doesn't support it ... treat it as a bug. :)

I was recently given an old Travan tape drive and asked to do something
useful with it. The ide-scsi + st (+serverworks ide controller) combo
results in a hard lockup of the machine which I have not had the energy to
debug, so I turned to ide-tape (which seems to work). The system in
question debian stable, using udev to manage /dev.
The following patch to ide-tape.c allows udev to create the cdev nodes for
my drive.

I noticed that the same typo (i before c in associated) showed up twice

This patch fixes both of the instances I found with this mistake. The
typos are in comments and should have no affect on working code.

Patch from Todd Poynor
Add symbols for PXA2xx PWRMODE register M field that selects low-power
mode, replace unadorned constants. Honor power mode parameter of
pxa_cpu_suspend(mode), no longer force to 3 (sleep). Full Deep Sleep
low-power mode support for PXA27x is pending generic PM interfaces to
select more than 2 suspend-to-RAM-style power modes, but this is
expected soon. This can be hardcoded in the meantime by replacing the
pxa_cpu_suspend() parameter value. From David Burrage and Todd Poynor.
Try #2 removes one of the register copies and moves the code to save the
pxa_cpu_suspend parameter to immediately surround the call that requires
the parameter value be preserved.
