Otherwise an exported symbol from driver should be fine. It's actually what we would like to avoid. We have two potential provider driver that would need such an interface, and we have customer drivers that would be able to use any of these two, depending on which SoCs we're talking about. Maintaining some logic in each and every driver in that case to know which one of this symbol is to be called seems counterproductive and painful.
