    drm/radeon: properly handle mc_stop/mc_resume on evergreen+ (v2)

    - Stop the displays from accessing the FB
    - Block CPU access
    - Turn off MC client access

    This should fix issues some users have seen, especially
    with UEFI, when changing the MC FB location that result
    in hangs or display corruption.

    v2: fix crtc enabled check noticed by Luca Tettamanti

So in other words, your explanation Alex seems to be right. I'll be waiting if
anything has to be tested.
