Hi Will

I'm probing dw_mmc on Samsung SoC...

So i have some board specific data..

But i didn't want to add board specific data in dw_mmc.c
I want to use get_cd()/get_wd()/init()...So i asked to you..:)

If i need not the data information, i will not append them..
you're right, maybe "struct dw_mci" need not..(just example)

And i think that need card_detect irq-handler function..if we use pdata->init..isn't? :)

In future, if i need your help, can i ask to you?

Onemore...Did you test the dw_mmc..?
If you can answer, i want to know the performance..
