Unfortunately with DRA7 / AM57xx: at least 2 different PMICs -> DRA74/DRA72 evms. even across similar PMIC usage, different voltage rail usage accross evms: DRA74evm, x15/GPEVM, AM571x-IDK/AM572x-IDK -> they are not necessarily compatible. Example: some of them have Ganged voltage rail, others dont - few others are mixed. if you are trying to get common regulator usage -> it is kinda pretty hard given the freedom board designers are being given by TI.. OMAP5 was more controlled in terms of what specific configuration the board designers had to follow. that is no longer the case for DRA7/AM57 platforms. just my 2 cents here. -- Regards, Nishanth Menon -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
