Interesting point. That's probably best for Grant to comment on, because it depends on the long-term direction he wants to take with this. I suppose that an IORESOURCE_GPIO makes a lot of sense if we expect to keep having a flat system-wide gpio number space in the long run, similar to irq numbers. It would not fit well if we expect gpio numbers to be local to a gpio controller, with no unique global identifier for them, similar to how dma channels in the dma-engine subsystem are handled.
