As I commented in
http://marc.info/?l=linux-omap&m=121792042504348&w=2
I can't quite see why anything is using "omap_mmc_config" for
anything related to hsmmc ... it contains two structs that
don't match what the hsmmc driver understands.

Hi David Brownell,
Please see function omap_init_mmc() in file
arch/arm/plat-omap/devices.c
It is doing the device registration and pin muxing for mmc
depending upon the values initialized in structure omap_mmc_config.
Best Regards
Arun KS
