Hm, I thought you were introducing this to then use it in the denali
driver. Sorry, but I don't want to apply something that nobody needs.
If someone ever complains about a missing delay I'll point him to your
patch, but until then I'll keep the core unchanged.

This one is valid. I'll queue it to nand/next soon.

Thanks,
