This patchset is a v2 of a previous posting: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-October/298537.html v1 => v2 changelog - Removed stale hw_pci domain member - Reworked pci-mvebu domain handling according to review - Rebased against 3.18-rc3 and updated the logs - Dropped RFC status Original cover letter: ---- This patchset is a first RFC stab at removing the dependency on pci_sys_data domain field on ARM platforms and by replacing it with generic code that stashes the domain value in the pci_bus control structure, introduced in commit 41e5c0f81d3e676d671d96a0a1fafb27abfbd9 ("of/pci: Add pci_get_new_domain_nr() and of_get_pci_domain_nr()") commit 670ba0c8883b576d0aec28bd7a838358a4be1 ("PCI: Add generic domain handling") All the drivers converted (apart from PCIe designware, tested on iMX6SL) were only compile tested for lack of HW, so along some comments, testing and verifying that patchset does not break any existing platform are very appreciated. Code in drivers/pci/pci-mvebu.c has been changed to add a domain number to PCI resources by using the nr value coming from the setup pcibios32 callback, which may not be correct and should be considered a temporary solution waiting for review comments. The patchset removes entirely the pci_sys_data.domain field, since its usage is removed at the same time in the respective host controllers and ARM is made to select the configuration option CONFIG_PCI_DOMAINS_GENERIC by default, which compiles a domain_nr in the pci_bus structure so that the pci_domain_nr() look-up can rely on it.
