[PATCH v3 0/3] ARM: PCI: implement generic PCI host controller

[Will Deacon]

Hi,

This is version 3 of the patches previously posted here:

  v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-February/229679.html
  v2: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-February/232213.html

Changes since v2 include:

  - Tightening up of the DT requirements:
    * Must have at least a non-prefetchable memory region
    * "reg" property now defines a base and size for config space
    * bus-range property supported and used in conjunction with "reg"
    * device_type must be "pci"

  - Fixed bus mapping so we don't sleep in atomic

  - Updated compatible strings and file names to get rid of "arm"

  - Added a really dumb I/O space allocator

  - Moved a bunch of ->probe() into ->setup(). Note that I've not included
    Arnd's patch to propagate ->setup() failures back to ->probe(), so despite
    the use of devm_* to manage resource allocations, I still have explicit
    cleanup code on the failure paths.

All feedback welcome.

Will
