Merge branch 'acpi-scan' into acpi-pm

2015-07-29T21:57:51+00:00

Conflicts: drivers/acpi/scan.c The conflict is resolved by moving the just introduced acpi_device_is_first_physical_node() to bus.c and using the existing acpi_companion_match() from there. There will be an additional commit to combine the two.

ACPI / PM: Attach ACPI power domain only once

2015-07-28T07:50:42+00:00

Some devices, like MFD subdevices, share a single ACPI companion device so that they are able to access their resources and children. However, currently all these subdevices are attached to the ACPI power domain and this might cause that the power methods for the companion device get called more than once. In order to solve this we attach the ACPI power domain only to the first physical device that is bound to the ACPI companion device. In case of MFD devices, this is the parent MFD device itself.

ACPI / bus: Move ACPI bus type registration

2015-07-17T20:54:09+00:00

Move the registration of the ACPI bus type to acpi_bus_init() and avoid using ACPI going forward if it fails (too many things depend on the presence of the ACPI bus type). Signed-off-by: Rafael J. Wysocki

ACPI / scan: Move bus operations and notification routines to bus.c

2015-07-17T20:54:01+00:00

To reduce the size of scan.c and improve the readability of it, move code related to device notification, the definitions of the ACPI bus operations and the driver management code to drivers/acpi/bus.c. Signed-off-by: Rafael J. Wysocki

ACPI / scan: Move device matching code to bus.c

2015-07-17T20:53:52+00:00

To reduce the size of scan.c and improve the readability of it, move code related device matching into drivers/acpi/bus.c. Signed-off-by: Rafael J. Wysocki

ACPI / scan: Move sysfs-related device code to a separate file

2015-07-17T20:53:43+00:00

To reduce the size of scan.c and improve the readability of it, move all code related to device sysfs, modalias creation etc. to a new file called device_sysfs.c. Signed-off-by: Rafael J. Wysocki

ACPI / scan: Add support for ACPI _CLS device matching

2015-07-06T23:55:20+00:00

Device drivers typically use ACPI _HIDs/_CIDs listed in struct device_driver acpi_match_table to match devices. However, for generic drivers, we do not want to list _HID for all supported devices. Also, certain classes of devices do not have _CID (e.g. SATA, USB). Instead, we can leverage ACPI _CLS, which specifies PCI-defined class code (i.e. base-class, subclass and programming interface). This patch adds support for matching ACPI devices using the _CLS method. To support loadable module, current design uses _HID or _CID to match device's modalias. With the new way of matching with _CLS this would requires modification to the current ACPI modalias key to include _CLS. This patch appends PCI-defined class-code to the existing ACPI modalias as following. acpi::::..::: E.g: # cat /sys/devices/platform/AMDI0600:00/modalias acpi:AMDI0600:010601: where bb is th base-class code, ss is te sub-class code, and pp is the programming interface code Since there would not be _HID/_CID in the ACPI matching table of the driver, this patch adds a field to acpi_device_id to specify the matching _CLS. static const struct acpi_device_id ahci_acpi_match[] = { { ACPI_DEVICE_CLASS(PCI_CLASS_STORAGE_SATA_AHCI, 0xffffff) }, {}, }; In this case, the corresponded entry in modules.alias file would be: alias acpi*:010601:* ahci_platform Acked-by: Mika Westerberg Reviewed-by: Hanjun Guo Signed-off-by: Suravee Suthikulpanit Signed-off-by: Rafael J.
