This series reworks the OpenCAPI driver to split frontend
(driver interactions) from backend (hardware interactions).

This allows external drivers to utilise the core of the
generic OpenCAPI driver to communicate with specific
OpenCAPI hardware.

Alastair D'Silva (7):
  ocxl: Provide global MMIO accessors for external drivers
  ocxl: Allow external drivers to use OpenCAPI contexts
  ocxl: Split pci.c
  ocxl: Don't pass pci_dev around
  ocxl: Create a clear delineation between ocxl backend & frontend
  ocxl: afu_irq only deals with IRQ IDs, not offsets
  ocxl: move event_fd handling to frontend
