I'm not going to get the rest of the Versatile series wrapped up for
3.20, but I think the PCI support is ready and would like to get it in.
I have not fixed the resource registration for /proc/iomem and irq
fixup as those issues are being worked on for a common fix.
Bjorn, Can you please take the whole series unless you prefer arm-soc
to.
v2:
- Added MAINTAINERS entry
- Based on generic PCI config accessors
- Module license fix
- Comment whitespace fix

+* ARM Versatile Platform Baseboard PCI interface
+
+PCI host controller found on the ARM Versatile PB board's FPGA.
+
+Required properties:
+- compatible: should contain "arm,versatile-pci" to identify the Versatile PCI
+ controller.
+- reg: base addresses and lengths of the pci controller. There must be 3
+ entries:
+ - Versatile specific registers
+ - Self Config space
+ - Config space
+- #address-cells: set to <3>
+- #size-cells: set to <2>
+- device_type: set to "pci"
+- bus-range: set to <0 0xff>
+- ranges: ranges for the PCI memory and I/O regions
+- #interrupt-cells: set to <1>
+- interrupt-map-mask and interrupt-map: standard PCI properties to define
+ the mapping of the PCI interface to interrupt numbers.
+
+Example:
+
+pci-controller@10001000 {
+ compatible = "arm,versatile-pci";
+ device_type = "pci";
+ reg = <0x10001000 0x1000

This converts the Versatile PCI host code to a platform driver using
the commom DT parsing and setup. The driver uses only an empty ARM
pci_sys_data struct and does not use pci_common_init_dev init function.
The old host code will be removed in a subsequent commit when Versatile
is completely converted to DT.
I've tested this on QEMU with the sym53c8xx driver in both i/o and
memory mapped modes.
