Now, from a s/w perspective, If we would like to have it so that we can configure tHigh and tLow based on devices, electrical characteristics on a bus, not just speed of the bus, the current implementation would probably need to change(I think). " maybe take tHigh, tLow as a platform data input to the driver? that could allow scaling for all boards I wonder?
