Folks with Tegra20-based boards (Compulab, Avionics Design, etc.) - please check my DT node settings for address, GPIOs (CD, WP, and power, if utilized), and width. I tried to keep everything the same as the tegra_mmc_init() function args that were removed, plus integrating what was in the Linux kernel DTS files for your board(s). Please also do a quick functional test to ensure everything still works as before with the MMC devices on your board(s).
Stephen, please check the boards you are familiar with (Whistler, PAZ00, Trimslice, Harmony) that I may not have here in AZ.
Thanks,
Tom

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.
