Hi Miroslav,
sorry for delay.
There is no significant difference between configs. I think the problem is in VDD regulator, in our design we do not use PMU. I think omap_hsmmc fails to load because of this :
[ 2.114389] omap_hsmmc 48060000.mmc: unable to get vmmc regulator -517
[ 2.135340] platform 48060000.mmc: Driver omap_hsmmc requests probe deferral
Is there a way to disable PMU at all ?
