Hi maintainer,
We found a problem that a panic happen when cpu was hot-removed. We also trace
the problem according to the calltrace information.
An endless loop happen because value head is not equal to value tail forever in
the function qi_check_fault( ).
The location code is as follows:

One should not do any assumptions on the stare of the fimd hardware
during driver initialization, so to properly reset fimd before enabling
IOMMU, one should ensure that all power domains and clocks are really
enabled. This patch adds pm_runtime and clocks management in the
fimd_clear_channel() fun
