I think this will leave every other board that uses omap_hsmmc
without any card caps.

What about adding something like this:


diff --git a/drivers/mmc/host/omap_hsmmc.c b/drivers/mmc/host/omap_hsmmc.c
index 8900bae..f2548f1 100644
--- a/drivers/mmc/host/omap_hsmmc.c

+ if (!((mmc->caps & MMC_CAP_SD) ||

omap_hsmmc_conf_bus_power(host);
