Really, you should have a bit-bang M6800 bus driver and binding and then the binding for the LCD ctrl looks the same whether you are bit-banging it or not. That's a bit more work though. Maybe you could split the binding like this, but keep a monolithic driver for now. The driver can just fetch the GPIOs from the parent (bus controller) node. And you'd have to work out probing the driver. > Memory-mapped configurations are not yet supported. I guess this would require faulting on some address and then bit-banging the access. That sounds fun... Rob
