Yeah I buy this concept, it's a good way to share this code.

I've tried a few times to get this driver working on the S8815 Calao
dongle version of Nomadik 8815, but failed miserably (I managed
to get DMA and MMC working, which I will likely try to merge.)
I'm still trying to figure out why sometimes now and then.

So this doesn't make anything worse anyway.

Thanks for this nice patch set!
