Hi guys,

At the moment, parport_write_control on the PC can enable/disable
interrupts from the port, and also control the direction of the data

We already have enable_irq/disable_irq in the interface, and I'd like to
add set_direction(int), where the argument is zero for forward. Also, I'd
like to enforce that parport_write_control only affects control lines, and
doesn't have side effects any more. I would then try to banish

Do people think this is a good idea, or should parport_write_control act
like writing the control register on a PC architecture, and other
architectures have to emulate?

Let me know what you think. This would be happening in 2.3 of course, not
