    PCI: Implement devm_pci_remap_cfgspace() · 490cb6dd
    Lorenzo Pieralisi authored
    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.
