Hi,
i want to write an SDIO driver. There is not much information of
what an SDIO driver is
supposed to do or any sample sdio drivers.

I have a few questions regarding that:

1) What is an SDIO Driver?.

2) Is SDIO a protocol/standard to which all devices confirm?.

3) Is it a generic driver ?. (Same for a set of devices) or
different for each device?
Suppose i want to run an SDIO WLAN Card?. will the
manufacturer support it or
an will a Generic Driver "drive" it?

4) What is a SD Driver?

5) What are the differences between SD Driver and SDIO Driver?.

6) Are there any sample/Open Source SDIO drivers available in Linux
Kernel or else where?.If, not when can one expect/is anyone working on
it currently?.
