Changes in v4: - restore pci_free_resource_list() in error path of of_pci_get_host_bridge_resources() Changes in v3: - refactor series to be both bisectable and simpler while reworking of_pci_get_host_bridge_resources() - include of_pci_get_host_bridge_resources() removal - include devm_of_pci_get_host_bridge_resources() error path fixes - effectively, no functional changes to v2 Changes in v2: - patch 1: commit message reworking as suggested by Lorenzo - patch 3-6: split-up as suggested by Bjorn - patch 8: new - patch 10: select PCI_DOMAINS from PCI_HOST_GENERIC, rather than allowing manual choice, as suggested by Lorenzo This primarily enables to unbind the generic PCI host controller without leaving lots of memory leaks behind. A previous proposal patch 5 was rejected because of those issues [1]. The fixes have been validated in the Jailhouse setup, where we add and remove a virtual PCI host controller on hypervisor activation/ deactivation, with the help of kmemleak. Besides that, there is tiny PCI API cleanup at the beginning and support for manually enabled PCI domains at the end that enables the Jailhouse scenario.
