[PATCH 0/21] ACPI / PM: Switch ACPI bus type and drivers to dev_pm_ops

[PATCH 0/21] ACPI / PM: Switch ACPI bus type and drivers to dev_pm_ops

[Rafael J. Wysocki]

Hi all,

The following patchset converts the ACPI bus type and all of the ACPI drivers
to the power management handling based on struct dev_pm_ops.  It does that in
the following way:

(1) The (unused) pm_message_t argument is dropped from the ACPI driver suspend
    callback throughout the tree (patch [1/21]).

(2) A struct dev_pm_ops object is defined for the ACPI bus type (patches
    [2-3/21]) in such a way that
    (a) driver callbacks from struct acpi_device_ops are executed for drivers
        that provide them,
    (b) driver callbacks from struct dev_pm_ops are executed for drivers that
        provide them,
    (c) 0 is returned for the remaining drivers.
    Only suspend/resume, freeze/thaw, poweroff/restore bus type callbacks are
    defined, because they are sufficient for the transition (they are removed
    later on anyway).

(3) All ACPI drivers that use PM callbacks are converted to the PM handling
    based on struct dev_pm_ops (patches [4-18/21]).

(4) The ACPI bus type is modified not to execute driver callbacks from
    struct acpi_device_ops any more (patch [19/21]).  This affects several
    x86 platform drivers and the ACPI power meter driver too.

(5) The driver PM callbacks in struct acpi_device_ops are removed
    (patch [20/21]).

(6) The ACPI bus type PM callbacks added in step (2) are dropped, because they
    aren't necessary any more (the PM core will execute the driver callbacks
    directly now).

As a result, the redundant bus type level of PM handling between ACPI drivers
and the PM core is eliminated and the ACPI drivers are now able to define
runtime PM callbacks, proper hibernation callbacks and late/early callbacks
for system suspend/resume.

The patchset has been tested on Toshiba Portege R500 and more testing is in
the works.  If there are no objections, I'd like to push if for 3.6 through
the linux-pm tree.

If you want to give it a go, it's available from the pm-acpi branch of the
linux-pm tree.  Please note, however, that this branch will be rebased, because
it is based on the linux-pm tree's linux-next branch at the moment.

Thanks,
Rafael

[PATCH 1/21] ACPI / PM: Drop pm_message_t argument from device suspend callback

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@sisk.pl>

None of the drivers implementing the ACPI device suspend callback
uses the pm_message_t argument of it, so this argument may be dropped
entirely from that callback.  This will simplify switching the ACPI
bus type to PM handling based on struct dev_pm_ops.

[PATCH 3/21] ACPI / PM: Make acpi_bus_type use driver struct dev_pm_ops callbacks

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@sisk.pl>

Modify acpi_bus_type so that it executes PM callbacks provided
by drivers through their struct dev_pm_ops objects, if present,
while still allowing the legacy ACPI PM callbacks to take precedence.
This will make it possible to convert ACPI drivers one by one to
handling PM through struct dev_pm_ops instead of the legacy way.

The code added by this change is temporary and will be removed
when all of the drivers in question have been switched over to
the PM handling based on struct dev_pm_ops.

[PATCH 19/21] ACPI / PM: Do not execute legacy driver PM callbacks

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@sisk.pl>

Since all ACPI drivers in the tree should have been switched
to power management handling based on struct dev_pm_ops,
modify the ACPI bus type driver so that is doesn't execute
legacy driver power management callbacks from the functions
pointed to by the members of the acpi_bus_pm structure.

[PATCH 21/21] ACPI / PM: Drop PM callbacks from the ACPI bus type

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@sisk.pl>

Since the ACPI bus type's PM callbacks only execute the driver ones
without doing anything else, they can be dropped, because the driver
callbacks will be executed by the PM core directly if bus type
(or other subsystem) callbacks are not present.

[PATCH missing/21] classmate-laptop: Use struct dev_pm_ops for power management

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@sisk.pl>

Make the classmate-laptop driver define its PM callbacks through
a struct dev_pm_ops object rather than by using legacy PM hooks
in struct acpi_device_ops.

Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

Hi all,

I overlooked the classmate-laptop driver in the ACPI conversion to PM
handling based on struct dev_pm_ops, so this one should go after [17/21] and
the next patches should be renumbered.

Thanks,
Rafael

Make the fujitsu-tablet driver define its PM callbacks through
a struct dev_pm_ops object rather than by using legacy PM hooks
in struct acpi_device_ops.

Hi all,

Another driver overlooked during the ACPI conversion to PM handling based on
struct dev_pm_ops, sorry about that.

This one should go after the classmate-laptop patch I've just posted.

Thanks,
Rafael

Good plan.  Would need to merge w/ my tree only if we run into conflicts.
