Hi William,
Just a question: You mark these regulators as always-on, so they'll
never be shut off even if the device is suspended. Is that because the
mmc driver can't deal with reinitializing the mmc/sd-card if the card
has been shut off while suspended or is there some other reason to
mark them always-on?
