Hello,
I am still seeing core domain to be ON on a 4460 board. The following
is the prcm debug output.
I am not sure whats keeping the core domain to be ON. I compared with
a system on which core has hit retention. But could not find anything
different other than some are IDLE vs Disabled.
Can anyone help me on this please?
