NAME
       pci_bus_alloc_resource - allocate a resource from a parent bus

SYNOPSIS
       int pci_bus_alloc_resource(struct pci_bus * bus, struct resource * res,
                                  resource_size_t size, resource_size_t align,
                                  resource_size_t min, unsigned long type_mask,
                                  resource_size_t (*alignf) (void *, const struct resource *, resource_size_t, resource_size_t),
                                  void * alignf_data);

ARGUMENTS
       bus
           PCI bus

       res
           resource to allocate

       size
           size of resource to allocate

       align
           alignment of resource to allocate

       min
           minimum /proc/iomem address to allocate

       type_mask
           IORESOURCE_* type flags

       alignf
           resource alignment function

       alignf_data
           data argument for resource alignment function

DESCRIPTION
       Given the PCI bus a device resides on, the size, minimum address, alignment and type, try
       to find an acceptable resource allocation for a specific device resource.
