So far, the pin muxing part is working (needs some polishing, but the foundation is here), with device tree bindings. I think the pin muxing could be used for Orion as well. Now, I'm planning to start working on the gpio + gpio interrupts parts of the driver, and I'm wondering how to interact with your work on the matter. My understanding is that the new way of doing a pinmux+gpio driver is to implement it in drivers/pinctrl/, which I have started doing. Should I continue working on a drivers/pinctrl/ driver for mvebu for Armada 370/XP, and then we see together if it makes sense to extend to Orion, and if so, what changes are needed?
