The card-detect GPIO is certainly low-active on Tamonten. I'm not quite sure why things worked before, but I guess it was due to the MMC core assuming the CD GPIO to be low-active unless otherwise specified and the Tegra DT code didn't pass the GPIO flags to the core. Anyway, I've verified that on Tamonten the same change doesn't break anything, card detect still works as expected with this patch series applied, so if Joseph could carry the Tamonten change as part of this patch it'd be great.
