Hi Konrad,

  Yes, I did check system suspend use case after flattening and there is 
no crash seen.

  The only issue I observed (both before and after flattening) is that 
waking up from bus suspend, there is an enumeration failure on second 
port in host mode, and an xHCI CMD_RUN timeout occurs. The issue is gone 
if we keep controller GDSC flags as RET_ON (not the right solution 
though). But this issue has nothing to do with flattening. I will sync 
up with clocks team and try to fix that host mode issue.

Regards,
Krishna,
