haiku/headers/os/drivers/ACPI.h
Jérôme Duval c20e9eefcd added a jam rule AddDriverRegistrationToHaikuImage to add device mappings on the image
commented the insertion of the attribute name in patterns in the case of a string attribute
notify_probe_by_file chooses a module based on a bus specific suffix
dm_register_child_device has a parameter to optionally check the support for the node
added scanning of bus devices after the boot filesystem is mounted
fixed dm_rescan, locking was misbehaving
fixed SYSTEM_DRIVER_REGISTRATION definition
added B_DRIVER_MAPPING attributes for PCI and ACPI devices:
  %vendor%_%device% for PCI, hid_%hid% and type_%type% for ACPI
moved acpi_device_module_info definition to public ACPI.h
