Yes it is a big help. However, I would like to make this change in a follow-on series. It involves changing the code to stop hard-coding the GPIOs. But there are many GPIOs involved, not just this bridge chip, and not just the LCD. So I think we need a separate series after this one to move the GPIOs to the device tree.
