This patchset adds device-tree support to the Tegra MMC driver. All device config is done via properties in the DT files instead of hard-coded config options/function arguments.
I've tested this on my Seaboard and everything works fine, including card detect. For the other T20 boards, I've used the Linux kernel DTS files for the sdhci nodes where there wasn't one already, or expanded the info that was already there. Everything builds fine, but I haven't tested anything but Seaboard.
unfortunately, this is still no go on PAZ00.

any ideas?
I'm going to be gone for a few days, but I think Stephen agreed to look into it. He has a PAZ00 board.
Thanks,
