I have started working on a pinctrl driver for mvebu, which would
handle pin muxing (MPP) + gpio + gpio interrupts.
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?
Thanks,
Thomas
