I don't have the permission to merge on u-boot-mmc git. 
I have the permission to merge on just u-boot-pmic..But I don't know whether it's the best way to apply this into my u-boot-pmic or not. :)

I had been already reviewed about this patch..
So if want to pick this, I think there is no problem about applied together with below patches.
