    Subject[PATCH v2 00/10] PCI: endpoint: Make host reboot handling more robust
    Date
    Hello,

    This is the follow up series of [1], to improve the handling of host reboot in
    the endpoint subsystem. This involves refining the PERST# and Link Down event
    handling in both the controller and function drivers.

    Testing
    =======

    This series is tested on Qcom SM8450 based development board with both MHI_EPF
    and EPF_TEST function drivers.

    Dependency
    ==========

    This series depends on [1] and [2].
