* ACPI / scan: Introduce struct acpi_scan_handlerRafael J. Wysocki2013-01-30
| | | | | | | | | | | | | | | | | | | | | | Introduce struct acpi_scan_handler for representing objects that will do configuration tasks depending on ACPI device nodes' hardware IDs (HIDs). Currently, those tasks are done either directly by the ACPI namespace scanning code or by ACPI device drivers designed specifically for this purpose. None of the above is desirable, however, because doing that directly in the namespace scanning code makes that code overly complicated and difficult to follow and doing that in "special" device drivers leads to a great deal of confusion about their role and to confusing interactions with the driver core (for example, sysfs directories are created for those drivers, but they are completely unnecessary and only increase the kernel's memory footprint in vain).

| | * ACPICA: Resources: Split interrupt share/wake bits into two fields.Bob Moore2013-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These two bits are merged at the external interface level for the IRQ, Interrupt, and GpioInt resource descriptors. However, these bits are logically independent and there is no need to keep them merged internally. Therefore, this change splits the bits into "sharable" and "wake capable" fields within the resource manager. This simplifies drive code that needs to examine these bits. Aaron Lu, Bob Moore.

Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 210 lines of 20121018 divergence.diff. The ACPICA source codes uses a totally different indentation style from the Linux to be compatible with other users (operating systems or BIOS). Indentation differences are critical to the release automation. There are two causes related to the "indentation" that are affecting the release automation: 1. The ACPICA -> Linux release process is: ACPICA source -- acpisrc - hierarchy - indent -> linuxized ACPICA source -- diff -> linuxized ACPICA patch (x) -- human intervention -> linuxized ACPICA patch (o) Where 'x' means "cannot be directly applied to the Linux" 'o' means "can be directly applied to the Linux" Different "indent" version or "indent" options used in the "indent" step will lead to different divergences. The version of "indent" used for the current release process is: GNU indent 2.2.11 The options of "indent" used for the current release process is: -npro -kr -i8 -ts8 -sob -l80 -ss -ncs 2. Manual indentation prettifying work in the Linux side will also harm the automatically generated linuxized ACPICA patches, making them impossible to apply directly. This patch fixes source code differences caused by the two causes so that the "human intervention" can be reduced in the future. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

For this purpose, it is necessary to be able to add symbolic links to attribute groups. For this reason, add sysfs helper functions for adding/removing symbolic links to/from attribute groups, sysfs_add_link_to_group() and sysfs_remove_link_from_group(), respectively.

Unfortunately, however, this was a mistake, because all devices depending on power resources should be treated this way (i.e. they should be resumed when all power resources required by their D0 state have been turned on) and for the majority of those devices the ACPI core can figure out by itself which (physical) devices depend on what power resources. For this reason, replace the code added by commit 0090def6 with a new, much more straightforward, mechanism that will be used internally by the ACPI core and remove all references to that code from kernel subsystems using ACPI. For the cases when there are (physical) devices that should be resumed whenever a not directly related ACPI device node goes into D0 as a result of power resources configuration changes, like in the SATA case, add two new routines, acpi_dev_pm_add_dependent() and acpi_dev_pm_remove_dependent(), allowing subsystems to manage such dependencies. Convert the SATA subsystem to use the new functions accordingly. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

For this reason, drop acpi_bus_add() and make all its callers use acpi_bus_scan() directly instead of it. Additionally, rearrange the code in acpi_scan_init() slightly to improve the visibility of the acpi_update_all_gpes() call in there. Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All callers of acpi_bus_trim() pass 1 (true) as the second argument of it, so remove that argument entirely and change acpi_bus_trim() to always behave as though it were 1.

| * | | ACPI / PCI: Rework the setup and cleanup of device wakeupRafael J. Wysocki2013-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the ACPI wakeup capability of PCI devices is set up in two different places, partially in acpi_pci_bind() where runtime wakeup is initialized and partially in platform_pci_wakeup_init(), where system wakeup is initialized. The cleanup is only done in acpi_pci_unbind() and it only covers runtime wakeup. Use the new .setup() and .cleanup() callbacks in struct acpi_bus_type to consolidate that code and do the setup and the cleanup each in one place. Signed-off-by: Rafael J.
