Good :-) Hopefully the explanation in PATCH 5/5 is also clear enough.

Thanks for the testing. However, I wonder why you think those changes
are need to get mvneta to work fine with the 'standby' mode ? While I
do agree that they are need for the 'mem' mode, they shouldn't be
needed for the 'standby' mode. For now, the standby mode only puts the
CPU into deep-idle, and that's all: all devices remain powered on, and
they don't lose their state.
