Thanks, this patch looks good. But could we invert the logic and use
fixed_direction_mask as that feels more natural to me?

And for legacy reasons, so we don't have to change the drivers:

if (!fixed_direction_mask && fixed_direction_output)
	fixed_direction_mask = ~1

Or we just go ahead and change the two drivers. Up to you.
