Date: Sat, 2 Feb 2013 11:40:42 +0000
Subject: [PATCH] MIPS: pci-ar724x: convert into a platform driver
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.

Date: Sat, 2 Feb 2013 13:18:54 +0000
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.

Static resources become impractical when multiple

change the probe routine to get those from there

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.
