The code is moved to the drivers/pci/host directory and turned into a proper platform driver, adding MSI and DT support while at it. Other PCI host controller drivers can be added to that directory in an attempt to make it easier to factor out common code. Patches 1 to 3 add generic OF helpers to parse a PCI node's ranges property as well as obtain the device and function numbers from a node's reg property. Patch 4 introduces a new MSI chip infrastructure which is required to make multiple platform-specific implementations of the MSI support functions coexist peacefully. Patches 5 and 6 move some of the Tegra specific code around to allow it to be used from outside the arch/arm/mach-tegra directory. Patch 7 moves the Tegra PCIe controller driver to the drivers/pci/host directory and turns it into a proper platform driver. It also adds MSI (based on patches by NVIDIA) and DT support. Patches 8 to 11 add device tree based probing for the TEC, Harmony and TrimSlice boards. Finally the default configuration for Tegra is updated in patch 12.
