Is the interrupt only available on GPIO1?
Some devices can route this to GPIO2 IIRC.
I'm not sure how that would be supported, I think we would need to add interrupt names to DT so users could specify which gpio they wired their IRQ lines to.
interrupt = <&host 23>; interrupt-name = "gpio2";
or similar?
You could also use pinctrl an require the user to mux the interrupt in whatever fashion makes sense for their device.
If done at that layer then no change is needed in the driver right? We just request and use the IRQ passed to us from i2c data.
