    Yes, that makes sense.
    Hi Gary and Ryan,
    Can you please tell us what is the actual parent clock source of LPC IP?
    I mean the operational clock of LPC IP hardware block, not the interface

I don't understand here what is holding Bios here but by initializing this LPC clock let bios boot.
