s/exteral/external in the subject line and other places.
I think that makes sense to extend the simple power sequence provider
to add a regulator since many SDIO chips may needed it but it seems
from the commit message of patch 06/12 that you don't actually need
a regulator but to toggle a WL_REG_ON pin in your WiFi chip.
I'll answer to that patch though.
