The introduction of the pci_remap_cfgspace() interface allows PCI host controller drivers to map PCI config space through a dedicated kernel interface. Current PCI host controller drivers use the devm_ioremap_*() devres interfaces to map PCI configuration space regions so in order to update them to the new pci_remap_cfgspace() mapping interface a new set of devres interfaces should be implemented so that PCI host controller drivers can make use of them. Introduce two new functions in the PCI kernel layer and Devres documentation: - devm_pci_remap_cfgspace() - devm_pci_remap_cfg_resource() so that PCI host controller drivers can make use of them to map PCI configuration space regions.
