It should ideally be computed based on the timing parameters of the transmitter, but until we figure out how to do so, I don't think it blocks de-staging the driver. Moving to drivers/media/ doesn't mean everything has to be perfect, we can continue improving the driver after the move. > Despite that I can't say if that driver is ready to be moved out of staging or > not. > > Laurent, do you have any preference in which order they should be applied?
