+commit 58d2e9bcd682d76bcb9575dc56c85f1d82a81bfa upstream.
+
+The patch converts the pci-ar724x driver into a
+platform driver. This makes it possible to register
+the PCI controller as a plain platform device.

+Subject: [PATCH] MIPS: avoid possible resource conflict in
+ register_pci_controller
+
+commit 222831787704c9ad9215f6b56f975b233968607c upstream.
+
+The IO and memory resources of a PCI controller
+might already have a parent resource set when
+they are passed to 'register_pci_controller'.
+
+If the parent resource is set, the request_resource
+call will fail due to resource conflict and the
+current code will not be able to register the
+PCI controller.
+
+Use the parent resource if it is available in the
+request_resource call to avoid the isssue.

+Subject: [PATCH] MIPS: pci-ar724x: use dynamically allocated PCI controller
+ structure
+
+commit 908339ef25b1d5e80f1c6fab22b9958174708b4a upstream.
+
+The current code uses static variables to store the
+PCI controller specific data. This works if the system
+contains one PCI controller only, however it becomes
+impractical when multiple PCI controllers are present.
+
+Move the variables into a dynamically allocated controller
+specific structure, and use that instead of the static
+variables.

+Subject: [PATCH] MIPS: pci-ar724x: remove static PCI IO/MEM resources
-Get those from the platform device instead.
+commit 34b134aebda89888b6985b7a3139e9cbdf209236 upstream.
+
+Static resources become impractical when multiple
+PCI controllers are present. Move the resources
+into the platform device registration code and
+change the probe routine to get those from there
+platform device's resources.

+Subject: [PATCH] MIPS: pci-ar724x: setup command register of the PCI
+ controller
+
+commit 12401fc28d40aa5bf8bda6991a96b6d7a3dae3ac upstream.
+
+The command register of the PCI controller is
+not initialized correctly by the bootloader on
+some boards and this leads to non working PCI
+bus.
+
+Add code to initialize the command register
+from the Linux code to avoid this.
