I suppose we could, but that is only possible after this round of "moderization", i.e. usage of CLOCKSOURCE_OF_DECLARE() et al. Plus the move will require a bunch of mechanical crap such as read_aux_reg() which only ARC defines (similar to headaches Noam had for his clksrc). So if we could agree on the sanity of this round of changes, I can work towards the imminent move into drivers. Thx, -Vineet
