This series adds the last bits for allowing a CXL Type2 driver to obtain
a CXL region linked to the device HDM decoders committed by the BIOS,
with the driver being the sfc network driver.
Changes from v27:
- patch 1: make driver probe failing if error in efx_cxl_init (Dan)
- patch 4: add unmapping if error after efx_cxl_init (Dave)
- patch 4/5: move cxl_pio_initialised from patch 4 to patch 5 (Dave)
Tested in the cxl_for_7.3 branch.
Alejandro Lucero (5):
sfc: add cxl support
cxl/sfc: Map cxl regs
cxl/sfc: Initialize dpa without a mailbox
sfc: obtain and map cxl range using devm_cxl_probe_mem
sfc: support pio mapping based on cxl
