Subject: [PATCH v3 07/34] PCI: deprecate pci_scan_bus_parented()
Date: Fri, 28 Oct 2011 16:26:05 -0600	[thread overview]
Message-ID: <20111028222605.30729.48907.stgit@bhelgaas.mtv.corp.google.com> (raw)
In-Reply-To: <20111028222432.30729.8431.stgit@bhelgaas.mtv.corp.google.com>

Users of pci_scan_bus_parented() should be converted to use either
    pci_scan_root_bus() (preferred, but also calls pci_bus_add_devices)
or
    pci_create_root_bus()
    pci_scan_child_bus()

Since pci_scan_bus_parented(), I'm marking it deprecated now and will
actually remove it later.

+What:	pci_scan_bus_parented()
+When:	3.5
+Why:	The pci_scan_bus_parented() interface creates a new root bus.  The
+	bus is created with default resources (ioport_resource and
+	iomem_resource) that are always wrong, so we rely on arch code to
+	correct them later.  Callers of pci_scan_bus_parented() should
+	convert to using pci_scan_root_bus() so they can supply a list of
+	bus resources when the bus is created.
