ACPI / PM: Fix unused function warnings for CONFIG_PM_SLEEP

2012-08-10T11:35:32Z

According to compiler warnings, several suspend/resume functions in ACPI drivers are not used for CONFIG_PM_SLEEP unset, so add #ifdefs to prevent them from being built in that case. Signed-off-by: Rafael J. Wysocki

ACPI: Use struct dev_pm_ops for power management in the button driver

2012-07-01T11:31:01Z

Make the ACPI button 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

ACPI button: remove unused procfs I/F

2011-03-23T03:20:35Z

Remove unused ACPI button procfs interface. Only /proc/acpi/button/lid/LID/state remains. Signed-off-by: Zhang Rui Signed-off-by: Len Brown

ACPI / Button: Avoid disabling wakeup unnecessarily on remove

2011-02-24T18:58:53Z

If a button device had already been enabled to wake up the system from sleep states before the button driver saw it, the driver shouldn't disable the device's wakeup capability when being detached from the device. Signed-off-by: Rafael J. Wysocki

ACPI: Remove the wakeup.run_wake_count device field

2011-02-24T18:58:53Z

The wakeup.run_wake_count ACPI device field is only used by the PCI runtime PM code to "protect" devices from being prepared for generating wakeup signals more than once in a row. However, it really doesn't provide any protection, because (1) all of the functions it is supposed to protect use their own reference counters effectively ensuring that the device will be set up for generating wakeup signals just once and (2) the PCI runtime PM code uses wakeup.run_wake_count in a racy way, since nothing prevents acpi_dev_run_wake() from being called concurrently from two different threads for the same device. Remove the wakeup.run_wake_count ACPI device field which is unnecessary, confusing and used in a wrong way. Signed-off-by: Rafael J. Wysocki

ACPI / PM: Report wakeup events from buttons

2011-01-07T06:18:16Z

Since ACPI buttons and lids can be configured to wake up the system from sleep states, report wakeup events from these devices. Signed-off-by: Rafael J. Wysocki Signed-off-by: Len Brown

ACPI / PM: Use device wakeup flags for handling ACPI wakeup devices

2011-01-07T06:17:41Z

There are ACPI devices (buttons and the laptop lid) that can wake up the system from sleep states and have no "physical" companion devices. The ACPI subsystem uses two flags, wakeup.state.enabled and wakeup.flags.always_enabled, for handling those devices, but they are not accessible through the standard device wakeup infrastructure. User space can only control them via the /proc/acpi/wakeup interface that is not really convenient (e.g. the way in which devices are enabled to wake up the system is not portable between different systems, because it requires one to know the devices' "names" used in the system's ACPI tables). To address this problem, use standard device wakeup flags instead of the special ACPI flags for handling those devices. In particular, use device_set_wakeup_capable() to mark the ACPI wakeup devices during initialization and use device_set_wakeup_enable() to allow or disallow them to wake up the system from sleep states. Rework the /proc/acpi/wakeup interface to take these changes into account. Signed-off-by: Rafael J. Wysocki Signed-off-by: Len Brown

ACPICA: Remove wakeup GPE reference counting which is not used

2010-07-07T02:34:26Z

After the previous patch that introduced acpi_gpe_wakeup() and modified the ACPI suspend and wakeup code to use it, the third argument of acpi_{enable|disable}_gpe() and the GPE wakeup reference counter are not necessary any more. Remove them and modify all of the users of acpi_{enable|disable}_gpe() accordingly. Also drop GPE type constants that aren't used any more. Signed-off-by: Rafael J.
