ACPI 5.0 specification introduces enumeration support for SPB buses. This
patch set adds the UART serial bus enumeration support to Linux using such
mechanism.

NOTE: The [PATCH 3/3] is only for the demonstration purpose and should not
      be merged into any of the published Linux source tree.

Lv Zheng (3):
  UART: Add UART subsystem as a bus.
  ACPI / UART: Add ACPI enumeration support for UART bus.
  UART: Add dummy devices to test the enumeration.
