See individual patches for changes from previous version. Fixed up sashiko reported issues. Series adds a 'type2_test' module parameter where it setup a mock type2 hierarchy with a mock type2 accelerator device directly under a root port that has an auto region setup. It also includes a CXL fix that was encountered when running tests with the new code.
