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. Best regards, -- Javier Martinez Canillas Open Source Group Samsung Research America
