Subject: [PATCH v2 0/7] Refactor OCXL driver to allow external drivers to use it

From: Alastair D'Silva <alastair@...ilva.org>

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.

Changelog:
V2:
  - Reorder patches as some required structs that were only available later
  - Add dev.release implementation for ocxl_file_info to address warning on
    driver unload (ocxl: Create a clear delineation...)
  - Set output var irq_id in ocxl_afu_irq_alloc (ocxl: afu_irq only deals...)
  - Bump copyright year (ocxl: Provide global MMIO accessors...,
	ocxl: Split pci.c)

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