Apart from the con_id thing I commented, I don't see huge problems converting the ACPI GPIO helpers to this new interface. One thing that is special to ACPI is that we have two kind of GPIO "connections": GpioIo - a normal GPIO that the driver can toggle or read values GpioInt - this is specifically used as a GPIO interrupt The drivers should be able to distinguish between the two. Currently we have an extra parameter in acpi_get_gpio_by_index(..., &info) that can be used for this. However, with the new gpiod_get() I'm not sure how we are supposed to do this now? Anyway, that shouldn't prevent merging this patch set. I'm sure that we can come up with some working solution :-) -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
