- * pci_iomap - create a virtual mapping cookie for a PCI BAR
- * @dev: PCI device that owns the BAR
- * @bar: BAR number
- * @maxlen: length of the memory to map
- *
- * Using this function you will get a __iomem address to your device BAR.
- * You can access it using ioread*() and iowrite*(). These functions hide
- * the details if this is a MMIO or PIO address space and will just do what
- * you expect from them in the correct way.
- *
- * @maxlen specifies the maximum length to map. If you want to get access to
- * the complete BAR without checking for its length first, pass %0 here.
