Should be in linux-next/master. Nice! However, it seems the OPP-v2 table takes precedence over the old one. When a default OPP-v2 table is supplied in the device tree, if the bootloader supplies an OPP table the old way it won't be taken into account. So if I understood correctly, this won't work here for the BG2Q.
