The regression is card detect ends up refering to a valid GPIO -> yeah as a result the upcoming DVI driver is broken without this patch. given that commit bf56f0a6668cd was intended to fix cd, it did not do it cleanly - hence my claim of regression.

Tony,
this is a regression introduced in my commit for .37-rc1. any chance
of this making to one of 37 rc cycles? I can re-post this patch
including l-a if that is the path you'd like.
Regards,
Nishanth Menon

[PATCH] OMAP4: Pandaboard: Fixing MMC card detect gpio line
The .gpio_cd member of omap2_hsmmc_info is not initialized. This
will default to zero. On Pandaboard this interferes with gpio line
assigned for powering TFP410 DVI chip.
