Can I use this driver via SD card slot? #27

Hi,

I would like to run SDIO's WIFI on SDHCI host controller which supported SDIO. Can I run this driver with SDHCI host controller? Is it supported only via GPIO?

Best regards, Nobuhiro

This driver should work through a card slot as long as the host supports SDIO. Since there is no reset available on an SD slot, CH_PD and RST should be wired to deassert (pulled up) on power-up since SD and SDIO perform device reset by cycling power.
