Jean, can you comment on this? > > I fear I don't have the slightest idea of what you're talking about. > "Taking platform resources"? Sorry, I should have written a proper description of what I meant. Add to i2c_board_info the following struct resource *resource; which is defined in ioport.h I thought this actually allowed for gpio's but right now can't figure out how to handle them. What it definitely does handle cleanly is devices with multiple irq's. You basically get to query for resources by name so can pass lots of 'platform data' type stuff without having to define a specific structure for passing it in. > >> Dmitry isn't going to want that header in the linux/input directory. > > And he would be right.

I'd kind of assumed they moved out when i2c/chips went away, but never actually checked! > -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
