Can you please add some more information here about why we're not
clearing all the pdc irqs and only the ones that are listed in DT? Is
that because the pdc is shared between exception levels of the CPU and
so some irqs shouldn't be used? Does the DT binding need to change to
only list the hwirqs that are usable by the OS instead of the ones that
are usable for the entire system? The binding doesn't mention this at
all so I am just guessing here.
