    This change breaks booting on SCMI-based platforms such as ARCH_BRCMSTB.
    If I revert this change or boot with fw_devlink=permissive, then our
    systems boot again. From a quick look, the SCMI clock provider was never
    probed which means that our UART driver never got a chance to get its
    clock and we have no console -> timeout.

    Al, AFAICT you had started to analyze this before in the context of
    SCMI, do you mind sharing what you had found?

    Saravana, is there any debugging output that we can help provide?

    Thank you!
