I don't like this patch as is, as it seems like you are replacing the VMMC regulator that actually exist in HW by parsing a DT property. I think mmc_of_parse_voltage() shall *only* be used when the OCR mask (->ocr_avail) can't be fetched by using a regulator. Typically that's when the VMMC voltage levels are managed within the mmc controller itself. I don't have a strong opinion on how you solve that, but I guess you have two options. 1. Make sure the driver can be build and used both for CONFIG_REGULATOR and !CONFIG_REGULATOR. What you need to take care of then, is to assign the ->ocr_avail mask to a default value in the case when it can't be fetched from a regulator. Most mmc drivers has some kind of fall-back mechanism like this. For those SoC where you need/can control the VMMC regulator, make sure those enables CONFIG_REGULATOR to get the proper behaviour by omap_hsmmc. 2. Force omap_hsmmc to be build with CONFIG_REGULATOR.
